Globally, there are about 257 million chronic carriers of hepatitis B. HIV is one of the world's leading infectious killers; in 2010, approximately 30 million people were estimated to have died because of it since the beginning of
570-515: A positron emission tomography (PET) scanner while they were being stimulated by their partners. Brain changes were observed and compared between states of rest, sexual stimulation, faked orgasm, and actual orgasm. Differences were reported in the brains of men and women during stimulation. Changes in brain activity were observed in both sexes, as regions associated with behavioral control, fear, and anxiety shut down. Regarding these, Gert Holstege said in an interview with The Times , "What this means

After the initial orgasm, subsequent orgasms for women may be stronger or more pleasurable as
950-451: A refractory period . The refractory period is the recovery phase after orgasm during which it is physiologically impossible for a man to have additional orgasms. In 1966, Masters and Johnson published pivotal research about the phases of sexual stimulation. Their work included women and men, and, unlike Alfred Kinsey in 1948 and 1953, tried to determine the physiological stages before and after orgasm. Masters and Johnson argued that, in

Although disability-related pain, including as a result of cancer , and mobility impairment can hamper sexual intercourse, in many cases, the most significant impediments to sexual intercourse for individuals with a disability are psychological. In particular, people who have a disability can find sexual intercourse daunting due to issues involving their self-concept as
1330-435: A "dry orgasm"). Prepubescent boys have dry orgasms. Dry orgasms can also occur as a result of retrograde ejaculation , or hypogonadism . Men may also ejaculate without reaching orgasm, which is known as anorgasmic ejaculation . They may also achieve orgasm by stimulation of the prostate ( see below ). The traditional view of male orgasm is that there are two stages: emission accompanying orgasm, almost instantly followed by

Between 1988 and 2002, the percentage of people in the U.S. who had sexual intercourse between the ages of 15 and 19 fell from 60 to 46 percent for never-married males, and from 51 to 46 percent for never-married females. In humans, sexual intercourse and sexual activity in general have been reported as having health benefits as varied as increased immunity by increasing
1900-445: A clinical context, orgasm is usually defined strictly by the muscular contractions involved during sexual activity, along with the characteristic patterns of change in heart rate, blood pressure, and often respiration rate and depth. This is categorized as the sudden discharge of accumulated sexual tension during the sexual response cycle, resulting in rhythmic muscular contractions in the pelvic region. Definitions of orgasm vary and there

The main phonological changes occurred during the Hellenistic and Roman period (see Koine Greek phonology for details): In all its stages, the morphology of Greek shows an extensive set of productive derivational affixes , a limited but productive system of compounding and a rich inflectional system. Although its morphological categories have been fairly stable over time, morphological changes are present throughout, particularly in

The Greek alphabet consists of 24 letters, each with an uppercase ( majuscule ) and lowercase ( minuscule ) form. The letter sigma has an additional lowercase form (ς) used in the final position of a word: In addition to the letters, the Greek alphabet features a number of diacritical signs : three different accent marks ( acute , grave , and circumflex ), originally denoting different shapes of pitch accent on

According to one estimation, " Homeric Greek is probably closer to Demotic than 12-century Middle English is to modern spoken English ". Greek is spoken today by at least 13 million people, principally in Greece and Cyprus along with a sizable Greek-speaking minority in Albania near
3040-504: A form of safe sex and contraception. Condoms are widely recommended for the prevention of sexually transmitted infections (STIs). According to reports by the National Institutes of Health (NIH) and World Health Organization (WHO), correct and consistent use of latex condoms reduces the risk of HIV/AIDS transmission by approximately 85–99% relative to risk when unprotected. Condoms are rarely used for oral sex and there
3230-604: A lack of "dialogue around this population's human right to consensual sexual expression, undertreatment of menstrual disorders, and legal and systemic barriers". Women with intellectual disability may lack sexual health care and sex education. They may not recognize sexual abuse. Consensual sexual intercourse is not always an option for some. Those with intellectual disability may have limited knowledge and access to contraception, screening for sexually transmitted infections and cervical cancer. Sexual intercourse may be for reproductive, relational, or recreational purposes. It often plays
3420-449: A lack of communication between sexual partners about what is needed for the woman to reach orgasm, feelings of sexual inadequacy in either partner, a focus on only penetration (vaginal or otherwise), and men generalizing women's trigger for orgasm based on their own sexual experiences with other women. Scholars state "many couples are locked into the idea that orgasms should be achieved only through intercourse [vaginal sex]" and that "[e]ven
3610-517: A man's penis into another person's rectum, but may also mean the use of sex toys or fingers to penetrate the anus, or oral sex on the anus ( anilingus ), or pegging . Oral sex consists of all the sexual activities that involve the use of the mouth and throat to stimulate genitalia or anus. It is sometimes performed to the exclusion of all other forms of sexual activity, and may include the ingestion or absorption of semen (during fellatio ) or vaginal fluids (during cunnilingus ). Fingering involves

It was proposed that this 'addictive behavior' be classified in DSM-5 as an impulsive–compulsive behavioral disorder. Addiction to sexual intercourse is thought to be genetically linked. Those having an addiction to sexual intercourse have a higher response to visual sexual cues in the brain. Those seeking treatment will typically see

It is manifested by hypersomnia and hypersexuality and remains relatively rare. Sexual activity can directly cause death , particularly due to coronary circulation complications, which is sometimes called coital death, coital sudden death or coital coronary. However, coital deaths are significantly rare. People, especially those who get little or no physical exercise, have
4370-553: A pleasurable feeling. Ejaculation may continue for a few seconds after the euphoric sensation gradually tapers off. It is believed that the exact feeling of "orgasm" varies from one man to another. After ejaculation, a refractory period usually occurs, during which a man cannot achieve another orgasm. This can last anywhere from less than a minute to several hours or days, depending on age and other individual factors. There have been very few studies correlating orgasm and brain activity in real time. One study examined 12 healthy women using
4560-605: A primary form of sexual activity. Researchers commonly use sexual intercourse to denote penile–vaginal intercourse while using specific words, such as anal sex or oral sex , for other sexual behaviors. Scholars Richard M. Lerner and Laurence Steinberg state that researchers also "rarely disclose" how they conceptualize sex "or even whether they resolved potential discrepancies" in conceptualizations of sex. Lerner and Steinberg attribute researchers' focus on penile–vaginal sex to "the larger culture's preoccupation with this form of sexual activity", and have expressed concern that
4750-462: A receptive partner during anal intercourse. The study said that fewer women reported engaging in anal sex than other partnered sexual behaviors. It was estimated that 10% to 14% of women aged 18 to 39 years old practiced anal sex in the past 90 days, and that most of the women who engage in anal sex said they practiced it once a month or a few times a year. The prevalence of sexual intercourse has been compared cross-culturally. In 2003, Michael Bozon of
4940-461: A role in personal decisions about sexual intercourse or other sexual activity, such as decisions about virginity , or legal and public policy matters. Religious views on sexuality vary significantly between different religions and sects of the same religion, though there are common themes, such as prohibition of adultery. Reproductive sexual intercourse between non-human animals is more often called copulation , and sperm may be introduced into
5130-474: A series of muscular contractions in the pelvic area that includes the vagina, the uterus, and the anus. For some women, on some occasions, these contractions begin soon after the woman reports that the orgasm has started and continue at intervals of about one second with initially increasing, and then reducing intensity. In some instances, the series of regular contractions is followed by a few additional contractions or shudders at irregular intervals. In other cases,
5320-862: A series of rhythmic contractions. Most women find these contractions very pleasurable. Researchers from the University Medical Center of Groningen in the Netherlands correlated the sensation of orgasm with muscular contractions occurring at a frequency of 8–13 Hz centered in the pelvis and measured in the anus. They argue that the presence of this particular frequency of contractions can distinguish between voluntary contraction of these muscles and spontaneous involuntary contractions, and appears to more accurately correlate with orgasm as opposed to other metrics like heart rate that only measure excitation. They assert that they have identified "[t]he first objective and quantitative measure that has
5510-416: A sexual being, or a partner's discomfort or perceived discomfort. Temporary difficulties can arise with alcohol and sex , as alcohol can initially increase interest through disinhibition but decrease capacity with greater intake; however, disinhibition can vary depending on the culture. People with mental disabilities also are subject to challenges in participating in sexual intercourse. This can include

In addition to physical stimulation, orgasm can be achieved from psychological arousal alone, such as during dreaming ( nocturnal emission for males or females) or by forced orgasm . Orgasm by psychological stimulation alone was first reported among people who had spinal cord injury . Although sexual function and sexuality after spinal cord injury are very often impacted, this injury does not deprive one of

In many societies, it is normal for couples to have sexual intercourse while using some method of birth control, sharing pleasure and strengthening their emotional bond through sexual activity even though they are deliberately avoiding pregnancy. In humans and bonobos , the female undergoes relatively concealed ovulation so that male and female partners commonly do not know whether she
6460-418: A suitable psychological state . During sleep, a sex dream can trigger an orgasm and the release of sexual fluids. The health effects surrounding the human orgasm are diverse. There are many physiological responses during sexual activity, including a relaxed state created by prolactin, as well as changes in the central nervous system , such as a temporary decrease in the metabolic activity of large parts of

Sexual intercourse often remains possible after major medical treatment of the reproductive organs and structures. This is especially true for women. Even after extensive gynecological surgical procedures (such as hysterectomy , oophorectomy , salpingectomy , dilation and curettage , hymenotomy , Bartholin gland surgery, abscess removal, vestibulectomy , labia minora reduction, cervical conization , surgical and radiological cancer treatments and chemotherapy), sexual intercourse can continue. Reconstructive surgery remains an option for women who have experienced benign and malignant conditions. Men and women who have underwent extensive surgery should consult their medical team to understand how their treatment or surgery affects sex and how long they should wait before having sexual intercourse after

The 2010 NSSHB study reported that vaginal intercourse was practiced more than insertive anal intercourse among men, but that 13% to 15% of men aged 25 to 49 practiced insertive anal intercourse. Receptive anal intercourse was infrequent among men, with approximately 7% of men aged 14 to 94 years old having said that they were

Other studies report that the lack of sexual intercourse does not significantly result in divorce, though it is commonly one of the various contributors to it. According to the 2010 National Survey of Sexual Health and Behavior (NSSHB), men whose most recent sexual encounter was with a relationship partner reported greater arousal, greater pleasure, fewer problems with erectile function, orgasm, and less pain during

One possible reason for this distinct biological feature may be formation of strong emotional bonds between sexual partners important for social interactions and, in the case of humans, long-term partnership rather than immediate sexual reproduction. Sexual dissatisfaction due to the lack of sexual intercourse is associated with increased risk of divorce and relationship dissolution, especially for men. Some research, however, indicates that general dissatisfaction with marriage for men results if their wives flirted with, erotically kissed or became romantically or sexually involved with another man ( infidelity ), and that this

During antiquity , Greek was by far the most widely spoken lingua franca in the Mediterranean world . It eventually became the official language of
14630-495: The Eastern Mediterranean , in what are today Southern Italy , Turkey , Cyprus , Syria , Lebanon , Israel , Palestine , Egypt , and Libya ; in the area of the Black Sea , in what are today Turkey, Bulgaria , Romania , Ukraine , Russia , Georgia , Armenia , and Azerbaijan ; and, to a lesser extent, in the Western Mediterranean in and around colonies such as Massalia , Monoikos , and Mainake . It
14820-516: The Indo-Iranian languages (see Graeco-Aryan ), but little definitive evidence has been found. In addition, Albanian has also been considered somewhat related to Greek and Armenian, and it has been proposed that they all form a higher-order subgroup along with other extinct languages of the ancient Balkans; this higher-order subgroup is usually termed Palaeo-Balkan , and Greek has a central position in it. Linear B , attested as early as
15010-657: The Phoenician script and was in turn the basis of the Latin , Cyrillic , Coptic , Gothic , and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer , ancient Greek literature includes many works of lasting importance in the European canon . Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of
15200-458: The Skene's glands (which are believed to be connected to the female G-spot), and can be sexually stimulated through anal sex, perineum massage or a vibrator. Much of the available information about prostate-induced orgasms comes from anecdotal reports by individuals, and the exact mechanisms by which such orgasms are produced are unclear; some sources suggest this occurs via stimulation of nerves in
15390-636: The anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia ), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo ), and vibrators . These activities involve physical intimacy between two or more people and are usually used among humans solely for physical or emotional pleasure. They can contribute to human bonding . There are different views on what constitutes sexual intercourse or other sexual activity, which can impact on views of sexual health . Although sexual intercourse , particularly
15580-489: The cerebral cortex while there is no change or increased metabolic activity in the limbic (i.e., "bordering") areas of the brain. These effects affect cultural views of orgasm, such as the beliefs that orgasm (and the frequency or consistency of it) is either important or irrelevant for satisfaction in a sexual relationship , and theories about the biological and evolutionary functions of orgasm. There are also sexual dysfunctions involving orgasm, such as anorgasmia . In
15770-441: The dorsal nerve of the clitoris . The G-spot area, which is considered to be interconnected with the clitoris, may also be indirectly stimulated during anal sex. Although the anus has many nerve endings, their purpose is not specifically for inducing orgasm, and so a woman achieving orgasm solely by anal stimulation is rare. Direct stimulation of the clitoris, a G-spot area, or both, while engaging in anal sex can help some women enjoy
15960-837: The mating process, especially for non-human animals; it can mean a variety of sexual activities between opposite-sex or same-sex pairings , but generally means the sexually reproductive act of transferring sperm from a male to a female or sexual procreation between a man and a woman. Although sex and having sex also most commonly denote penile–vaginal intercourse, sex can be significantly broad in its meaning and may cover any penetrative or non-penetrative sexual activity between two or more people. The World Health Organization (WHO) states that non-English languages and cultures use different words for sexual activity, "with slightly different meanings". Various vulgarisms , slang , and euphemisms are used for sexual intercourse or other sexual activity, such as fuck , screw , shag , and
16150-492: The nominal and verbal systems. The major change in the nominal morphology since the classical stage was the disuse of the dative case (its functions being largely taken over by the genitive ). The verbal system has lost the infinitive , the synthetically -formed future, and perfect tenses and the optative mood . Many have been replaced by periphrastic ( analytical ) forms. Pronouns show distinctions in person (1st, 2nd, and 3rd), number (singular, dual , and plural in
16340-421: The penis in males (typically accompanied by ejaculation ) and of the clitoris (and vagina ) in females. Sexual stimulation can be by masturbation , or with a sexual partner ( penetrative sex , non-penetrative sex , or other sexual activity ). Physical stimulation is not requisite though, as possibilities exist to reach orgasm through psychological means alone. And getting to orgasm may be difficult without
16530-560: The prostatic plexus surrounding the organ, others suggest it is via nerves within the prostate itself, and others say changes in the brain ( neuroplasticity ) are required to derive pleasure from prostate stimulation. Regardless, prostate-induced orgasms are often reported to be intensely pleasurable. Prostate stimulation can produce a deeper orgasm, described by some men as more widespread and intense, longer-lasting, and allowing for greater feelings of ecstasy than orgasm elicited by penile stimulation only. The practice of pegging (consisting of
16720-429: The tip of the penis , commonly described as a "throbbing" or "tingling" sensation. They eventually increase in speed and intensity as the orgasm approaches, until a final "plateau" (the orgasmic) pleasure is sustained for several seconds. During orgasm, a human male experiences rapid, rhythmic contractions of the anal sphincter , the prostate, and the bulbospongiosus muscles of the penis. The sperm are transmitted up
16910-437: The vasa deferentia from the testicles , into the prostate gland as well as through the seminal vesicles to produce what is known as semen . The prostate produces a secretion that forms one of the components of ejaculate. Except for in cases of a dry orgasm, contraction of the sphincter and prostate force stored semen to be expelled through the penis's urethral opening . The process takes from three to ten seconds and produces
17100-407: The woman on top position or the coital alignment technique , a technique combining the "riding high" variation of the missionary position with pressure-counterpressure movements performed by each partner in rhythm with sexual penetration, to maximize clitoral stimulation. Anal sex involves stimulation of the anus , anal cavity, sphincter valve or rectum ; it most commonly means the insertion of
17290-429: The "roof" of the vagina and can create pleasurable sensations when stimulated, intense sexual pleasure (including orgasm) from vaginal stimulation is occasional or otherwise absent because the vagina has significantly fewer nerve endings than the clitoris. The greatest concentration of vaginal nerve endings are at the lower third (near the entrance) of the vagina. Sex educator Rebecca Chalker states that only one part of
17480-736: The "widespread, unquestioned equation of penile–vaginal intercourse with sex reflects a failure to examine systematically 'whether the respondent's understanding of the question [about sexual activity] matches what the researcher had in mind'". This focus can also relegate other forms of mutual sexual activity to foreplay or contribute to them not being regarded as "real sex", and limits the meaning of rape . It may also be that conceptually conflating sexual activity with vaginal intercourse and sexual function hinders and limits information about sexual behavior that non-heterosexual people may be engaging in, or information about heterosexuals who may be engaging in non–vaginal sexual activity. Studies regarding
17670-468: The 'main event'" and that "because women reach orgasm through intercourse less consistently than men," they are likelier than men to fake an orgasm to satisfy their sexual partners. In 1991, scholars from the Kinsey Institute stated, "The truth is that the time between penetration and ejaculation varies not only from man to man, but from one time to the next for the same man." They added that
17860-487: The French Institut national d'études démographiques conducted a cross-cultural study titled "At what age do women and men have their first sexual intercourse?" In the first group of the contemporary cultures he studied, which included sub-Saharan Africa (listing Mali , Senegal and Ethiopia ), the data indicated that the age of men at sexual initiation in these societies is at later ages than that of women, but
18050-486: The Greek alphabet since approximately the 9th century BC. It was created by modifying the Phoenician alphabet , with the innovation of adopting certain letters to represent the vowels. The variant of the alphabet in use today is essentially the late Ionic variant, introduced for writing classical Attic in 403 BC. In classical Greek, as in classical Latin, only upper-case letters existed. The lower-case Greek letters were developed much later by medieval scribes to permit
18240-495: The Greek language was the Cypriot syllabary (also a descendant of Linear A via the intermediate Cypro-Minoan syllabary ), which is closely related to Linear B but uses somewhat different syllabic conventions to represent phoneme sequences. The Cypriot syllabary is attested in Cyprus from the 11th century BC until its gradual abandonment in the late Classical period, in favor of the standard Greek alphabet. Greek has been written in
18430-629: The Greek verb have likewise remained largely the same over the course of the language's history but with significant changes in the number of distinctions within each category and their morphological expression. Greek verbs have synthetic inflectional forms for: Many aspects of the syntax of Greek have remained constant: verbs agree with their subject only, the use of the surviving cases is largely intact (nominative for subjects and predicates, accusative for objects of most verbs and many prepositions, genitive for possessors), articles precede nouns, adpositions are largely prepositional, relative clauses follow
18620-685: The Greek-Albanian border. A significant percentage of Albania's population has knowledge of the Greek language due in part to the Albanian wave of immigration to Greece in the 1980s and '90s and the Greek community in the country. Prior to the Greco-Turkish War and the resulting population exchange in 1923 a very large population of Greek-speakers also existed in Turkey , though very few remain today. A small Greek-speaking community
18810-793: The Philippines, fertility awareness and the rhythm method are emphasized while disapproval is expressed with regard to other contraceptive methods. Worldwide, sterilization is a more common birth control method, and use of the intrauterine device (IUD) is the most common and effective way of reversible contraception. Conception and contraception are additionally a life-and-death situation in developing countries , where one in three women give birth before age 20; however, 90% of unsafe abortions in these countries could be prevented by effective contraception use. The National Survey of Sexual Health and Behavior (NSSHB) indicated in 2010 that "1 of 4 acts of vaginal intercourse are condom-protected in
19000-637: The U.S. (1 in 3 among singles)," that "condom use is higher among black and Hispanic Americans than among white Americans and those from other racial groups," and that "adults using a condom for intercourse were just as likely to rate the sexual extent positively in terms of arousal, pleasure and orgasm than when having intercourse without one". Penile–vaginal penetration is the most common form of sexual intercourse. Studies indicate that most heterosexual couples engage in vaginal intercourse nearly every sexual encounter. The National Survey of Sexual Health and Behavior (NSSHB) reported in 2010 that vaginal intercourse
19190-456: The activity and reach orgasm during it. The aforementioned orgasms are sometimes referred to as anal orgasms , but sexologists and sex educators generally believe that orgasms derived from anal penetration are the result of the relationship between the nerves of the anus, rectum, clitoris or G-spot area in women, and the anus's proximity to the prostate and relationship between the anal and rectal nerves in men, rather than orgasms originating from
19380-404: The acute during the late 20th century, and it has only been retained in typography . After the writing reform of 1982, most diacritics are no longer used. Since then, Greek has been written mostly in the simplified monotonic orthography (or monotonic system), which employs only the acute accent and the diaeresis. The traditional system, now called the polytonic orthography (or polytonic system),
19570-402: The ancient language; singular and plural alone in later stages), and gender (masculine, feminine, and neuter), and decline for case (from six cases in the earliest forms attested to four in the modern language). Nouns, articles, and adjectives show all the distinctions except for a person. Both attributive and predicative adjectives agree with the noun. The inflectional categories of
19760-522: The anus itself. For women, stimulation of the breast area during sexual intercourse or foreplay , or solely having the breasts fondled, can create mild to intense orgasms, sometimes referred to as a breast orgasm or nipple orgasm . Few women report experiencing orgasm from nipple stimulation. Before Komisaruk et al.'s functional magnetic resonance (fMRI) research on nipple stimulation in 2011, reports of women achieving orgasm from nipple stimulation relied solely on anecdotal evidence . Komisaruk's study
19950-456: The appropriate length for sexual intercourse is the length of time it takes for both partners to be mutually satisfied, emphasizing that Kinsey "found that 75 percent of men ejaculated within two minutes of penetration. But he didn't ask if the men or their partners considered two minutes mutually satisfying" and "more recent research reports slightly longer times for intercourse". A 2008 survey of Canadian and American sex therapists stated that
20140-405: The average time for heterosexual intercourse (coitus) was 7 minutes and that 1 to 2 minutes was too short, 3 to 7 minutes was adequate and 7 to 13 minutes desirable, while 10 to 30 minutes was too long. Anorgasmia is regular difficulty reaching orgasm after ample sexual stimulation, causing personal distress. This is significantly more common in women than in men, which has been attributed to
20330-469: The blood leaves the genitals. In the 1970s, Helen Singer Kaplan added the category of desire to the cycle, which she argued precedes sexual excitation. She stated that emotions of anxiety, defensiveness, and the failure of communication can interfere with desire and orgasm. In the late 1980s and after, Rosemary Basson proposed a more cyclical alternative to what had largely been viewed as a linear progression. In her model, desire feeds arousal and orgasm, and
20520-608: The body's production of antibodies and subsequent lower blood pressure , and decreased risk of prostate cancer . Sexual intimacy and orgasms increase levels of the hormone oxytocin (also known as "the love hormone"), which can help people bond and build trust. Oxytocin is believed to have a more significant impact on women than on men, which may be why women associate sexual attraction or sexual activity with romance and love more than men do. A long-term study of 3,500 people between ages 18 and 102 by clinical neuropsychologist David Weeks indicated that, based on impartial ratings of
20710-438: The body's response includes muscular spasms (in multiple areas), a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm (known as the resolution phase ) is typically a relaxing experience , after the release of the neurohormones oxytocin and prolactin , as well as endorphins (or "endogenous morphine "). Human orgasms usually result from physical sexual stimulation of
20900-405: The body, causing a mental state that is often described as transcendental, and with vasocongestion and associated pleasure comparable to that of a full-contractionary orgasm. For example, modern findings support the distinction between ejaculation and male orgasm. For this reason, there are views on both sides as to whether these can be accurately defined as orgasms. Orgasms can be achieved during
21090-453: The brain and possibly suggest key psychological differences between women. Regular difficulty reaching orgasm after ample sexual stimulation, known as anorgasmia , is significantly more common in women than in men ( see below ). In addition to sexual dysfunction being a cause for women's inability to reach orgasm, or the amount of time for sexual arousal needed to reach orgasm being variable and longer in women than in men, other factors include
21280-623: The bulbs of the clitoris—triangular, crescental masses of erectile tissue. O'Connell et al., who performed dissections on the female genitals of cadavers and used photography to map the structure of nerves in the clitoris, were already aware that the clitoris is more than just its glans and asserted in 1998 that there is more erectile tissue associated with the clitoris than is generally described in anatomical textbooks. They concluded that some females have more extensive clitoral tissues and nerves than others, especially having observed this in young cadavers as compared to elderly ones, and therefore whereas
21470-608: The central component to women's sexual satisfaction. The first major national surveys of sexual behavior in the US were the Kinsey Reports . Alfred Kinsey was the first researcher to harshly criticize Freud's ideas about female sexuality and orgasm when, through his interviews with thousands of women, Kinsey found that most of the women he surveyed could not have vaginal orgasms. He "criticized Freud and other theorists for projecting male constructs of sexuality onto women" and "viewed
21660-412: The clinical definition of orgasm, but this way of viewing orgasm is merely physiological, while there are also psychological, endocrinological, and neurological definitions of orgasm. In these and similar cases, the sensations experienced are subjective and do not necessarily involve the involuntary contractions characteristic of orgasm. In both sexes, they are extremely pleasurable and often felt throughout
21850-537: The clitoris as the main center of sexual response" and the vagina as "relatively unimportant" for sexual satisfaction, relaying that "few women inserted fingers or objects into their vaginas when they masturbated". He "concluded that satisfaction from penile penetration [is] mainly psychological or perhaps the result of referred sensation". Masters and Johnson's research into the female sexual response cycle , as well as Shere Hite 's, generally supported Kinsey's findings about female orgasm. Masters and Johnson's research on
22040-463: The clitoris is very sensitive after climax, making additional stimulation initially painful. Masters and Johnson argued that all women are potentially multiply orgasmic, but that multiply orgasmic men are rare, and stated that "the female is capable of rapid return to orgasm immediately following an orgasmic experience, if re-stimulated before tensions have dropped below plateau phase response levels". Though generally reported that women do not experience
22230-408: The clitoris, the cervix and the vaginal wall – where the G-spot is reported to be – when several women stimulated themselves in a functional magnetic resonance (fMRI) machine. "I think that the bulk of the evidence shows that the G-spot is not a particular thing," stated Barry Komisaruk , head of the research findings. "It's not like saying, 'What is the thyroid gland?' The G-spot is more of
22420-431: The clitoris, the urethral sponge, is in contact with the penis, fingers, or a dildo in the vagina. Hite and Chalker state that the tip of the clitoris and the inner lips, which are also very sensitive, are not receiving direct stimulation during penetrative intercourse. Because of this, some couples may engage in the woman on top position or the coital alignment technique to maximize clitoral stimulation. For some women,
22610-599: The concept of "vaginal orgasm" as separate from clitoral orgasm. In 1905, Freud stated that clitoral orgasms are purely an adolescent phenomenon and that upon reaching puberty, the proper response of mature women is a change-over to vaginal orgasms, meaning orgasms without any clitoral stimulation. While Freud provided no evidence for this basic assumption, the consequences of this theory were considerable. Many women felt inadequate when they could not achieve orgasm via vaginal intercourse alone, involving little or no clitoral stimulation, as Freud's theory made penile–vaginal intercourse
22800-485: The deposit of (usually) raw semen in the vagina of a woman, is in effect a substitute for intercourse and is often contrasted with 'normal intercourse' in this context. Reproductive methods also extend to gay and lesbian couples. For gay male pairings, there is the option of surrogate pregnancy; for lesbian couples, there is donor insemination in addition to choosing surrogate pregnancy. Some women use artificial insemination to become single mothers by choice . There are
22990-415: The digital manipulation of the clitoris, rest of the vulva , vagina or anus for the purpose of sexual arousal and sexual stimulation; it may constitute the entire sexual encounter or it may be part of mutual masturbation, foreplay or other sexual activities. Natural human reproduction involves penile–vaginal penetration, during which semen , containing male gametes known as sperm cells or spermatozoa,
23180-410: The disease , and patients can enjoy healthy and productive lives. In cases where infection is suspected, early medical intervention is highly beneficial in all cases. The CDC stated "the risk of HIV transmission from an infected partner through oral sex is much less than the risk of HIV transmission from anal or vaginal sex," but that "measuring the exact risk of HIV transmission as a result of oral sex
23370-510: The disorder, estimates for the prevalence of premature ejaculation vary significantly more than for erectile dysfunction. For example, the Mayo Clinic states, "Estimates vary, but as many as 1 out of 3 men may be affected by [premature ejaculation] at some time." Further, "Masters and Johnson speculated that premature ejaculation is the most common sexual dysfunction, even though more men seek therapy for erectile difficulties" and that this
23560-529: The epidemic. Of the 2.7 million new HIV infections estimated to occur worldwide in 2010, 1.9 million (70%) were in Africa . The World Health Organization also stated that the "estimated 1.2 million Africans who died of HIV-related illnesses in 2010 comprised 69% of the global total of 1.8 million deaths attributable to the epidemic." It is diagnosed by blood tests , and while no cure has been found, it can be controlled by management through antiretroviral drugs for
23750-452: The expression of a gene transcription factor called ΔFosB (delta FosB) in the brain's reward center ; consequently excessively frequent engagement in sexual activity on a regular (daily) basis can lead to the overexpression of ΔFosB, inducing an addiction to sexual activity. Sexual addiction or hypersexuality is often considered an impulse control disorder or a behavioral addiction. It has been linked to atypical levels of dopamine,
23940-499: The female is in estrus, and to engage in sex acts with same-sex partners . Like humans engaging in sexual activity primarily for pleasure, this behavior in these animals is also presumed to be for pleasure, and a contributing factor to strengthening their social bonds. Sexual intercourse may be called coitus , copulation , coition , or intercourse . Coitus is derived from the Latin word coitio or coire , meaning "a coming together or joining together" or "to go together", and
24130-431: The female's reproductive tract in non-vaginal ways among the animals, such as by cloacal copulation. For most non-human mammals , mating and copulation occur at the point of estrus (the most fertile period of time in the female's reproductive cycle), which increases the chances of successful impregnation . However, bonobos , dolphins and chimpanzees are known to engage in sexual intercourse regardless of whether
24320-448: The fertile window, a practice that is sometimes called 'timed intercourse'. Timed intercourse using urine tests that predict ovulation may help improve the rate of pregnancy and live births for some couples trying to conceive such as those who have been trying for less than 12-months and who are under 40 years old, however, it is not clear from medical evidence if timed intercourse improves the rate of ultra-sound confirmed pregnancies and it
24510-402: The first stage, "accessory organs contract and the male can feel the ejaculation coming; two to three seconds later the ejaculation occurs, which the man cannot constrain, delay, or in any way control" and that, in the second stage, "the male feels pleasurable contractions during ejaculation, reporting greater pleasure tied to a greater volume of ejaculate". They reported that, unlike females, "for
24700-525: The frequency of their orgasms and the amount of stimulation necessary to trigger an orgasm." Clitoral orgasms are easier to achieve because the glans of the clitoris , or clitoris as a whole, has more than 8,000 sensory nerve endings , which is as many (or more in some cases) nerve endings as are present in the human penis or glans penis . As the clitoris is homologous to the penis, it is the equivalent in its capacity to receive sexual stimulation. One misconception, particularly in older research publications,
24890-412: The front wall of the vagina is inextricably linked with the internal parts of the clitoris, stimulating the vagina without activating the clitoris may be next to impossible. In their 2009 published study, the "coronal planes during perineal contraction and finger penetration demonstrated a close relationship between the root of the clitoris and the anterior vaginal wall". Buisson and Foldès suggested "that
25080-439: The infinitive entirely (employing a raft of new periphrastic constructions instead) and uses participles more restrictively. The loss of the dative led to a rise of prepositional indirect objects (and the use of the genitive to directly mark these as well). Ancient Greek tended to be verb-final, but neutral word order in the modern language is VSO or SVO. Modern Greek inherits most of its vocabulary from Ancient Greek, which in turn
25270-645: The lack of sex education with regard to women's bodies, especially in sex-negative cultures, such as clitoral stimulation usually being key for women to orgasm. The physical structure of coitus favors penile stimulation over clitoral stimulation; the location of the clitoris then usually necessitates manual or oral stimulation in order for the woman to achieve orgasm. Approximately 25% of women report difficulties with orgasm, 10% of women have never had an orgasm, and 40% or 40–50% have either complained about sexual dissatisfaction or experienced difficulty becoming sexually aroused at some point in their lives. Vaginismus
25460-473: The lack of a knowledgeable healthcare provider trained and experienced in counseling those with intellectual disabilities on sexual intercourse. Those with intellectual disabilities may have hesitations regarding the discussion of the topic of sex, a lack of sexual knowledge and limited opportunities for sex education. In addition there are other barriers such as a higher prevalence of sexual abuse and assault. These crimes often remain underreported. There remains
25650-467: The late 15th century BC, was the first script used to write Greek. It is basically a syllabary , which was finally deciphered by Michael Ventris and John Chadwick in the 1950s (its precursor, Linear A , has not been deciphered and most likely encodes a non-Greek language). The language of the Linear B texts, Mycenaean Greek , is the earliest known form of Greek. Another similar system used to write
25840-402: The majority of females can only achieve orgasm by direct stimulation of the external parts of the clitoris, the stimulation of the more generalized tissues of the clitoris via intercourse may be sufficient for others. French researchers Odile Buisson and Pierre Foldès reported similar findings to that of O'Connell's. In 2008, they published the first complete 3D sonogram via medical ultrasound of
26030-655: The man the resolution phase includes a superimposed refractory period" and added that "many males below the age of 30, but relatively few thereafter, have the ability to ejaculate frequently and are subject to only very short refractory periods during the resolution phase". Masters and Johnson equated male orgasm and ejaculation and maintained the necessity for a refractory period between orgasms. There has been little scientific study of multiple orgasms in men. Dunn and Trost defined multiple male orgasms as "two or more orgasms with or without ejaculation and without, or with only very limited, de-tumescence (loss of erection) during one and
26220-621: The meaning of sexual intercourse sometimes come into conflict. While most consider penile–vaginal intercourse to be sex, whether anal or oral intercourse are considered sex is more debatable, with oral sex ranking lowest. The Centers for Disease Control and Prevention (CDC) stated that "although there are only limited national data about how often adolescents engage in oral sex, some data suggest that many adolescents who engage in oral sex do not consider it to be 'sex'; therefore they may use oral sex as an option to experience sex while still, in their minds, remaining abstinent". Upton et al. stated, "It
26410-524: The membership of Greece and Cyprus in the European Union, Greek is one of the organization's 24 official languages . Greek is recognized as a minority language in Albania, and used co-officially in some of its municipalities, in the districts of Gjirokastër and Sarandë . It is also an official minority language in the regions of Apulia and Calabria in Italy. In the framework of the European Charter for Regional or Minority Languages , Greek
26600-469: The men in his study who showed the same pattern of nipple stimulation activating genital brain regions. Masters and Johnson were some of the first researchers to study the sexual response cycle in the early 1960s, based on the observation of 382 women and 312 men. They described a cycle that begins with excitement as blood rushes into the genitals, then reaches a plateau during which they are fully aroused, which leads to orgasm, and finally resolution, in which
26790-441: The modern period. The division into conventional periods is, as with all such periodizations, relatively arbitrary, especially because, in all periods, Ancient Greek has enjoyed high prestige, and the literate borrowed heavily from it. Across its history, the syllabic structure of Greek has varied little: Greek shows a mixed syllable structure, permitting complex syllabic onsets but very restricted codas. It has only oral vowels and
26980-542: The more practices engaged in, the higher a woman's chance of having an orgasm. Women were more likely to reach orgasm in encounters including cunnilingus". Other studies suggest that women exposed to lower levels of prenatal androgens are more likely to experience orgasm during vaginal intercourse than other women. Kinsey, in his 1953 book Sexual Behavior in the Human Female , stated that exercise could bring about sexual pleasure, including orgasm. A review in 1990 on
27170-489: The most common way to achieve orgasm is by direct sexual stimulation of the clitoris (meaning consistent digital , oral , or other concentrated friction against the external parts of the clitoris). General statistics indicate that 70–80 percent of women require direct clitoral stimulation to achieve orgasm, although indirect clitoral stimulation (for example, via vaginal penetration) may also be sufficient. The Mayo Clinic stated, "Orgasms vary in intensity, and women vary in
27360-399: The noun they modify and relative pronouns are clause-initial. However, the morphological changes also have their counterparts in the syntax, and there are also significant differences between the syntax of the ancient and that of the modern form of the language . Ancient Greek made great use of participial constructions and of constructions involving the infinitive, and the modern variety lacks
27550-706: The older periods of Greek, loanwords into Greek acquired Greek inflections, thus leaving only a foreign root word. Modern borrowings (from the 20th century on), especially from French and English, are typically not inflected; other modern borrowings are derived from Albanian , South Slavic ( Macedonian / Bulgarian ) and Eastern Romance languages ( Aromanian and Megleno-Romanian ). Greek words have been widely borrowed into other languages, including English. Example words include: mathematics , physics , astronomy , democracy , philosophy , athletics , theatre, rhetoric , baptism , evangelist , etc. Moreover, Greek words and word elements continue to be productive as
27740-448: The outer third of the vagina tightens and narrows, while overall the vagina lengthens and dilates and also becomes congested from engorged soft tissue. Elsewhere in the body, myofibroblasts of the nipple- areolar complex contract, causing erection of the nipples and contraction of the areolar diameter, reaching their maximum at the start of orgasm. A woman experiences full orgasm when her uterus, vagina, anus, and pelvic muscles undergo
27930-569: The ovum, forming a new embryo . Pregnancy begins after the fertilized ovum is implanted in the lining of the uterus (the endometrium ). Pregnancy rates for sexual intercourse are highest during the menstrual cycle time from some five days before until approximately one day after ovulation (this is sometimes called the fertile window ). For optimal pregnancy chance, there are recommendations of vaginal intercourse every one or two days, or every two or three days. Some people who are trying to conceive may choose to time vaginal intercourse with
28120-618: The partners orient their hips to allow the penis to move back and forth in the vagina to cause friction, typically without fully removing the penis. In this way, they stimulate themselves and each other, often continuing until orgasm in either or both partners is achieved. For human females, stimulation of the clitoris plays a significant role in sexual activity; 70–80% of women require direct clitoral stimulation to achieve orgasm, though indirect clitoral stimulation (for example, via vaginal intercourse) may also be sufficient (see orgasm in females ). Because of this, some couples may engage in
28310-537: The pelvic floor could help address the sexual problems but that it was not well studied enough to recommend. Starting in at least 2007, the term, "coregasm" was used in popular media to refer to exercise-induced orgasm or in academic parlance termed exercise-induced sexual pleasure or EISP, and an extensive discussion of the "yogasm" occurred in a 2011 Daily Beast posting. A paper published in 2012 presented results of an online survey of women who had experienced an orgasm or other sexual pleasure during exercise. The paper
28500-698: The phrase "sleep together". The laws of some countries use the euphemism, carnal knowledge . Penetration of the vagina by the erect penis is additionally known as intromission , or by the Latin name immissio penis (Latin for "insertion of the penis"). The age of first sexual intercourse is called sexarche . Vaginal, anal and oral sex are recognized as sexual intercourse more often than other sexual behaviors. Sexual activity that does not involve penile-vaginal sex or other sexual penetration might be used to retain virginity (sometimes called technical virginity ) or labeled outercourse . One reason virginity loss
28690-604: The predominant sources of international scientific vocabulary . Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, or possibly earlier. The earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the world's oldest recorded living language . Among the Indo-European languages, its date of earliest written attestation
28880-445: The presence of other STIs. In 2005, the World Health Organization estimated that 123 million women become pregnant worldwide each year, and around 87 million of those pregnancies or 70.7% are unintentional. Approximately 46 million pregnancies per year reportedly end in induced abortion . Approximately 6 million U.S. women become pregnant per year. Out of known pregnancies, two-thirds result in live births and roughly 25% in abortions;
29070-403: The protection of a condom is often associated with emasculation because condoms prevent direct penile–to–skin genital contact. Sexual intercourse or other sexual activity can encompass various sexually stimulating factors ( physiological stimulation or psychological stimulation ), including different sex positions (such as the missionary position , the most common human sex position ) or
29260-520: The public media would lead one to believe the G-spot is a well-characterized entity capable of providing extreme sexual stimulation, yet this is far from the truth". Possible explanations for the G-spot were examined by Masters and Johnson, who were the first researchers to determine that the clitoral structures surround and extend along and within the labia. In addition to observing that the majority of their female subjects could only have clitoral orgasms, they found that both clitoral and vaginal orgasms had
29450-427: The refractory period may only last a few minutes, but last more than an hour in older men. An increased infusion of the hormone oxytocin during ejaculation is believed to be chiefly responsible for the refractory period, and the amount by which oxytocin is increased may affect the length of each refractory period. A scientific study to successfully document natural, fully ejaculatory, multiple orgasms in an adult man
29640-564: The remainder end in miscarriage. However, many more women become pregnant and miscarry without even realizing it, instead mistaking the miscarriage for an unusually heavy menstruation . The U.S. teenage pregnancy rate fell by 27 percent between 1990 and 2000, from 116.3 pregnancies per 1,000 girls aged 15–19 to 84.5. This data includes live births, abortions, and fetal losses. Almost 1 million American teenage women, 10% of all women aged 15–19 and 19% of those who report having had intercourse, become pregnant each year. Sexual activity can increase
29830-407: The same sexual encounter". Although, due to the refractory period, it is rare for men to achieve multiple orgasms, some men have reported having multiple, consecutive orgasms, particularly without ejaculation. There may not be an obvious refractory period, and the final orgasm may cause a refractory period. Multiple orgasms are more commonly reported in very young men than in older men. In younger men,
30020-443: The same stages of physical response. On this basis, they argued that clitoral stimulation is the source of both kinds of orgasms, reasoning that the clitoris is stimulated during penetration by friction against its hood; their notion that this provides the clitoris with sufficient sexual stimulation has been criticized by researchers such as Elisabeth Lloyd . Australian urologist Helen O'Connell's 2005 research additionally indicates
30210-610: The sexual feelings such as sexual arousal and erotic desires. Scientific literature focuses on the psychology of female orgasm significantly more than it does on the psychology of male orgasm, which "appears to reflect the assumption that female orgasm is psychologically more complex than male orgasm," but "the limited empirical evidence available suggests that male and female orgasm may bear more similarities than differences. In one controlled study by Vance and Wagner (1976), independent raters could not differentiate written descriptions of male versus female orgasm experiences". In women,
30400-473: The sexual response itself as exercise, reviewed the literature and stated that the field was poorly researched; it also said that studies had found that aerobic or isotonic exercise that resembles sexual activity or sexual positions can induce sexual pleasure, including orgasm. A 2007 review of the relationship between pelvic floor dysfunction and sexual problems in men and women found that they are commonly linked and suggested that physical therapy strengthening
30590-440: The special sensitivity of the lower anterior vaginal wall could be explained by pressure and movement of clitoris's root during a vaginal penetration and subsequent perineal contraction". Supporting a distinct G-spot is a study by Rutgers University , published 2011, which was the first to map the female genitals onto the sensory portion of the brain; brain scans showed that the brain registered distinct feelings between stimulating
30780-438: The stimulated clitoris, and republished it in 2009 with new research, demonstrating the ways in which erectile tissue of the clitoris engorges and surrounds the vagina, arguing that women may be able to achieve vaginal orgasm via stimulation of the G-spot because the highly innervated clitoris is pulled closely to the anterior wall of the vagina when the woman is sexually aroused and during vaginal penetration. They assert that since
30970-535: The stimulation accumulates. Discussions of female orgasm are complicated by orgasms in women typically being divided into two categories: clitoral orgasm and vaginal (or G-spot) orgasm. In 1973, Irving Singer theorized that there are three types of female orgasms; he categorized these as vulval , uterine, and blended, but because he was a philosopher, "these categories were generated from descriptions of orgasm in literature rather than laboratory studies". In 1982, Ladas, Whipple and Perry also proposed three categories:
31160-553: The stimulatory (plateau) phase and not to the orgasmic phase itself." Greek language Greek ( Modern Greek : Ελληνικά , romanized : Elliniká , [eliniˈka] ; Ancient Greek : Ἑλληνική , romanized : Hellēnikḗ ) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to Greece , Cyprus , Italy (in Calabria and Salento ), southern Albania , and other regions of
31350-437: The stressed vowel; the so-called breathing marks ( rough and smooth breathing ), originally used to signal presence or absence of word-initial /h/; and the diaeresis , used to mark the full syllabic value of a vowel that would otherwise be read as part of a diphthong. These marks were introduced during the course of the Hellenistic period. Actual usage of the grave in handwriting saw a rapid decline in favor of uniform usage of
31540-440: The subjects' photographs, sex on a regular basis is associated with people looking significantly chronologically younger. However this does not imply causality. Vaginal intercourse for the first time increases vaginal immune activity. Sexually transmitted infections (STIs) are bacteria , viruses or parasites that are spread by sexual contact, especially vaginal, anal, or oral intercourse, or unprotected sex . Oral sex
31730-622: The tenting type (derived from clitoral stimulation), the A-frame type (derived from G-spot stimulation), and the blended type (derived from clitoral and G-spot stimulation). In 1999, Whipple and Komisaruk proposed cervix stimulation as being able to cause a fourth type of female orgasm. Female orgasms by means other than clitoral or vaginal/G-spot stimulation are less prevalent in scientific literature and most scientists contend that no distinction should be made between "types" of female orgasm. This distinction began with Sigmund Freud , who postulated
31920-906: The term coitus, generally denotes penile–vaginal penetration and the possibility of creating offspring , it also commonly denotes penetrative oral sex and penile–anal sex, especially the latter. It usually encompasses sexual penetration, while non-penetrative sex has been labeled outercourse , but non-penetrative sex may also be considered sexual intercourse. Sex , often a shorthand for sexual intercourse , can mean any form of sexual activity. Because people can be at risk of contracting sexually transmitted infections during these activities, safer sex practices are recommended by health professionals to reduce transmission risk. Various jurisdictions place restrictions on certain sexual acts, such as adultery , incest , sexual activity with minors , prostitution , rape , zoophilia , sodomy , premarital sex and extramarital sex . Religious beliefs also play
32110-526: The time with intercourse, compared with 81 percent of the time during oral sex ( cunnilingus ). In the first large-scale empirical study worldwide to link specific practices with orgasm, reported in the Journal of Sex Research in 2006, demographic and sexual history variables were comparatively weakly associated with orgasm. Data was analyzed from the Australian Study of Health and Relationships,
32300-467: The topic came at the time of the second-wave feminist movement , and inspired feminists such as Anne Koedt , author of The Myth of the Vaginal Orgasm , to speak about the "false distinction" made between clitoral and vaginal orgasms and women's biology not being properly analyzed. Accounts that the vagina is capable of producing orgasms continue to be subject to debate because, in addition to
32490-446: The unnecessary use of these drugs because they are accompanied by serious risks such as increased chance of heart attack. The selective serotonin reuptake inhibitor (SSRI) and antidepressant drug dapoxetine has been used to treat premature ejaculation. In clinical trials, those with PE who took dapoxetine experienced sexual intercourse three to four times longer before orgasm than without the drug. Another ejaculation-related disorder
32680-433: The use of sex toys . Foreplay may precede some sexual activities, often leading to sexual arousal of the partners and resulting in the erection of the penis or natural lubrication of the vagina . It is also common for people to be as sexually satisfied by being kissed, touched erotically , or held as they are during sexual intercourse. Non- primate females copulate only when in estrus , but sexual intercourse
32870-506: The use of vaginal dilators . Additionally, the use of Botox as a medical treatment for vaginismus has been tested and administered. Painful or uncomfortable sexual intercourse may also be categorized as dyspareunia . Approximately 40% of males reportedly have some form of erectile dysfunction (ED) or impotence, at least occasionally. Premature ejaculation has been reported to be more common than erectile dysfunction, although some estimates suggest otherwise. Due to various meanings of
33060-399: The vagina is the physiological explanation for the conjectured G-spot. Having used MRI technology which enabled her to note a direct relationship between the legs or roots of the clitoris and the erectile tissue of the "clitoral bulbs" and corpora, and the distal urethra and vagina, she stated that the vaginal wall is the clitoris; that lifting the skin off the vagina on the side walls reveals
33250-479: The vagina's low concentration of nerve endings, reports of the G-spot's location are inconsistent—it appears to be nonexistent in some women and may be an extension of another structure, such as the Skene's gland or the clitoris, which is a part of the Skene's gland. In a January 2012 The Journal of Sexual Medicine review examining years of research into the existence of the G-spot, scholars stated that "[r]eports in
33440-447: The various stages of the Greek language are often emphasized. Although Greek has undergone morphological and phonological changes comparable to those seen in other languages, never since classical antiquity has its cultural, literary, and orthographic tradition been interrupted to the extent that one can speak of a new language emerging. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than
33630-529: The vernacular form of Modern Greek proper, and Katharevousa , meaning 'purified', a compromise between Dimotiki and Ancient Greek developed in the early 19th century that was used for literary and official purposes in the newly formed Greek state. In 1976, Dimotiki was declared the official language of Greece, after having incorporated features of Katharevousa and thus giving birth to Standard Modern Greek , used today for all official purposes and in education . The historical unity and continuing identity between
33820-471: The woman reports having an orgasm, but no pelvic contractions are measured at all. Women's orgasms are preceded by the erection of the clitoris and moistening of the opening of the vagina. Some women exhibit a sex flush , a reddening of the skin over much of the body due to increased blood flow to the skin. As a woman nears orgasm, the clitoral glans retracts under the clitoral hood , and the labia minora (inner lips) become darker. As orgasm becomes imminent,
34010-435: The word foreplay suggests that any other form of sexual stimulation is merely preparation for the 'main event.'... ...Because women reach orgasm through intercourse less consistently than men, they are more likely than men to have faked an orgasm ". Sex counselor Ian Kerner stated, "It's a myth that using the penis is the main way to pleasure a woman." He cites research concluding that women reach orgasm about 25 percent of
34200-574: Was a distinct dialect of Greek itself. Aside from the Macedonian question, current consensus regards Phrygian as the closest relative of Greek, since they share a number of phonological, morphological and lexical isoglosses , with some being exclusive between them. Scholars have proposed a Graeco-Phrygian subgroup out of which Greek and Phrygian originated. Among living languages, some Indo-Europeanists suggest that Greek may be most closely related to Armenian (see Graeco-Armenian ) or
34390-568: Was also used as the official language of government and religion in the Christian Nubian kingdoms , for most of their history. Greek, in its modern form, is the official language of Greece, where it is spoken by almost the entire population. It is also the official language of Cyprus (nominally alongside Turkish ) and the British Overseas Territory of Akrotiri and Dhekelia (alongside English ). Because of
34580-505: Was also used in Ancient Greek. Greek has occasionally been written in the Latin script , especially in areas under Venetian rule or by Greek Catholics . The term Frankolevantinika / Φραγκολεβαντίνικα applies when the Latin script is used to write Greek in the cultural ambit of Catholicism (because Frankos / Φράγκος is an older Greek term for West-European dating to when most of (Roman Catholic Christian) West Europe
34770-404: Was conducted at Rutgers University in 1995. During the study, six fully ejaculatory orgasms were experienced in 36 minutes, with no apparent refractory period. In both sexes, pleasure can be derived from the nerve endings around the anus and the anus itself, such as during anal sex . Men can achieve orgasms through prostate stimulation alone. The prostate is the male homologue (variation) to
34960-892: Was lower, with both men and women involved in sexual intercourse before any union formation; the study listed Switzerland, Germany and the Czech Republic as members of this group. Concerning United States data, tabulations by the National Center for Health Statistics report that the age of first sexual intercourse was 17.1 years for both males and females in 2010. The CDC stated that 45.5 percent of girls and 45.7 percent of boys had engaged in sexual activity by 19 in 2002; in 2011, reporting their research from 2006 to 2010, they stated that 43% of American unmarried teenage girls and 42% of American unmarried teenage boys have ever engaged in sexual intercourse. The CDC also reports that American girls will most likely lose their virginity to
35150-594: Was more closely matched; there were two sub-groups, however. In non-Latin, Catholic countries (Poland and Lithuania are mentioned), age at sexual initiation was higher, suggesting later marriage and reciprocal valuing of male and female virginity. The same pattern of late marriage and reciprocal valuing of virginity was reflected in Singapore and Sri Lanka . The study considered China and Vietnam to also fall into this group, though data were not available. In northern and eastern European countries, age at sexual initiation
35340-426: Was regarded as a medical treatment, and not a sexual release. The disorder has ceased to be recognized as a medical condition since the 1920s. As a man nears orgasm during stimulation of the penis, he feels an intense and highly pleasurable pulsating sensation of neuromuscular euphoria . These pulsating sensations originate from the contractions of pelvic floor muscles that begin in the anal sphincter and travel to
35530-400: Was the first to map the female genitals onto the sensory portion of the brain; it indicates that sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix, and that these reported orgasms are genital orgasms caused by nipple stimulation, and may be directly linked to the genital sensory cortex ("the genital area of the brain"). An orgasm
35720-580: Was under the control of the Frankish Empire ). Frankochiotika / Φραγκοχιώτικα (meaning 'Catholic Chiot') alludes to the significant presence of Catholic missionaries based on the island of Chios . Additionally, the term Greeklish is often used when the Greek language is written in a Latin script in online communications. The Latin script is nowadays used by the Greek-speaking communities of Southern Italy . The Yevanic dialect
35910-412: Was widely discussed in popular media when it was published. The authors of the paper said that research on the relationship between exercise and sexual response was still lacking. In men, the most common way of achieving orgasm is by physical sexual stimulation of the penis . This is usually accompanied by ejaculation , but it is possible, though also rare, for men to orgasm without ejaculation (known as
36100-673: Was written by Romaniote and Constantinopolitan Karaite Jews using the Hebrew Alphabet . In a tradition, that in modern time, has come to be known as Greek Aljamiado , some Greek Muslims from Crete wrote their Cretan Greek in the Arabic alphabet . The same happened among Epirote Muslims in Ioannina . This also happened among Arabic-speaking Byzantine rite Christians in the Levant ( Lebanon , Palestine, and Syria ). This usage
