93-587: It discusses witches' pacts with the devil , and detailed descriptions of witches’ powers and poisons. It also contains Guazzo's classification of demons , based on a previous work by Michael Psellus . The work is extensive and divided into three books. The first one is dedicated to explaining what magic consists of and what types of magic exist. It also describes various practices of witchcraft, such as pacts with Satan, witches' sabbaths , and sexual encounters with incubi and succubi demons. The same volume includes Guazzo's classification of demons. The second book

186-411: A genital ulcer ; even if they do not, they increase the risk of both acquiring and passing on HIV up to ten-fold. Hepatitis B can also be transmitted through sexual contact. 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

279-453: A manuscript is a stub . You can help Misplaced Pages by expanding it . Pact with the devil A deal with the Devil , also known as a Faustian bargain , is a cultural motif exemplified by the legend of Faust and the figure of Mephistopheles , as well as being elemental to many Christian traditions . According to traditional Christian belief about witchcraft , the pact is between

372-460: A stroke can also largely impact on the ability to engage in sexual intercourse. 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

465-426: A boy who is 1 to 3 years older than they are. 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

558-400: A demon, and each one had his own sigil . Books like The Lesser Key of Solomon (also known as Lemegeton Clavicula Salomonis ) give a detailed list of these signs, known as diabolical signatures. The Malleus Maleficarum discusses several alleged instances of pacts with the Devil, especially concerning women. It was considered that all witches and warlocks had made a pact with one of

651-504: 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

744-604: 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

837-517: 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

930-497: A neurotransmitter. This behavior is characterized by a fixation on sexual intercourse and disinhibition. 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

1023-430: A person and the Devil or another demon , trading a soul for diabolical favours, which vary by the tale, but tend to include youth, knowledge, wealth, fame and power. It was also believed that some people made this type of pact just as a sign of recognising the minion as their master, in exchange for nothing. The bargain is a dangerous one, as the price of the fiend's service is the wagerer's soul. For most religions,

1116-505: A physician for pharmacological management and therapy. One form of hypersexuality is Kleine–Levin syndrome . 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

1209-605: 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

1302-462: 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

1395-461: 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

1488-416: 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

1581-468: A slightly increased risk of triggering a heart attack or sudden cardiac death when they engage in sexual intercourse or any vigorous physical exercise that is engaged in on a sporadic basis. Regular exercise reduces, but does not eliminate, the increased risk. Sexual intercourse, when involving a male participant, often ends when the male has ejaculated, and thus the partner might not have time to reach orgasm . In addition, premature ejaculation (PE)

1674-429: A strong role in human bonding . 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

1767-522: A surgery. Obstacles that those with disabilities face with regard to engaging in sexual intercourse include pain, depression , fatigue, negative body image , stiffness, functional impairment, anxiety, reduced libido , hormonal imbalance, and drug treatment or side effects. Sexual functioning has been regularly identified as a neglected area of the quality of life in patients with rheumatoid arthritis . For those that must take opioids for pain control, sexual intercourse can become more difficult. Having

1860-416: A variety of safe sex methods that are practiced by heterosexual and same-sex couples, including non-penetrative sex acts, and heterosexual couples may use oral or anal sex (or both) as a means of birth control. However, pregnancy can still occur with anal sex or other forms of sexual activity if the penis is near the vagina (such as during intercrural sex or other genital-genital rubbing ) and its sperm

1953-1071: Is delayed ejaculation , which can be caused as an unwanted side effect of antidepressant medications such as fluvoxamine ; however, all SSRIs have ejaculation-delaying effects, and fluvoxamine has the least ejaculation-delaying effects. 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

2046-424: Is ejaculated through the penis into the vagina. The sperm passes through the vaginal vault , cervix and into the uterus , and then into the fallopian tubes . Millions of sperm are ejaculated to increase the chances of fertilization (see sperm competition ), but only one is sufficient to fertilize an egg or ovum . When a fertile ovum from the female is present in the fallopian tubes, the male gamete fertilizes

2139-483: Is "the most prevalent sexual behavior among men and women of all ages and ethnicities". Clint E. Bruess et al. stated that it "is the most frequently studied behavior" and is "often the focus of sexuality education programming for youth." Weiten et al. said that it "is the most widely endorsed and practiced sexual act in our society." Regarding oral or anal intercourse, the CDC stated in 2009, "Studies indicate that oral sex

2232-444: Is a form of assisted reproductive technology , which are methods used to achieve pregnancy by artificial or partially artificial means. For artificial insemination, sperm donors may donate their sperm through a sperm bank , and the insemination is performed with the express intention of attempting to impregnate the female; to this extent, its purpose is the medical equivalent of sexual intercourse. ICI insemination, which involves

2325-456: Is also known as vaginal intercourse or vaginal sex . Sexual penetration has been known by humans since the dawn of time, and has been an instinctive form of sexual behaviour and psychology among humans. Other forms of penetrative sexual intercourse include anal sex (penetration of 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

2418-509: Is also not clear if timed intercourse has an effect on a person's level of stress or their quality of life. Studies have shown no significant difference between different sex positions and pregnancy rate, as long as it results in ejaculation into the vagina. When a sperm donor has sexual intercourse with a woman who is not his partner and for the sole purpose of impregnating the woman, this may be known as natural insemination , as opposed to artificial insemination . Artificial insemination

2511-532: Is at lower ages than that of women; this group includes south European and Latin cultures (Portugal, Greece and Romania are noted) and such from Latin America (Brazil, Chile , and the Dominican Republic ). The study considered many Asian societies to also fall into this group, although matching data was only available from Thailand . In the third group, age of men and women at sexual initiation

2604-600: Is because "although an estimated 15 percent to 20 percent of men experience difficulty controlling rapid ejaculation, most do not consider it a problem requiring help, and many women have difficulty expressing their sexual needs". The American Urological Association (AUA) estimates that premature ejaculation could affect 21 percent of men in the United States. For those whose impotence is caused by medical conditions, prescription drugs such as Viagra , Cialis , and Levitra are available. However, doctors caution against

2697-411: Is common, and women often require a substantially longer duration of stimulation with a sexual partner than men do before reaching an orgasm. Scholars, such as Weiten et al., state that "many couples are locked into the idea that orgasms should be achieved only through intercourse [penile-vaginal sex]," that "the word foreplay suggests that any other form of sexual stimulation is merely preparation for

2790-502: Is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents." Oral sex is significantly more common than anal sex. 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

2883-420: Is deposited near the vagina's entrance and travels along the vagina's lubricating fluids; the risk of pregnancy can also occur without the penis being near the vagina because sperm may be transported to the vaginal opening by the vagina coming in contact with fingers or other non-genital body parts that have come in contact with semen. Safe sex is a relevant harm reduction philosophy and condoms are used as

2976-403: Is devoted to the diverse powers of witches, such as love spells, the creation of poisons and potions, and the ability to cause and cure diseases. The third and final book explains the various ways in which witchcraft can be cured or removed. It also explains the difference between possession and bewitchment, and details how to recognize a person possessed by a demon. There is a second edition of

3069-512: Is especially the case for men with a lower emotional and composite marital satisfaction. 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

3162-685: Is fertile at any given moment. 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

3255-602: Is involuntary tensing of the pelvic floor musculature, making coitus, or any form of penetration of the vagina, distressing, painful and sometimes impossible for women. It is a conditioned reflex of the pubococcygeus muscle, and is sometimes referred to as the PC muscle. Vaginismus can be hard to overcome because if a woman expects to experience pain during sexual intercourse, this can cause a muscle spasm, which results in painful sexual intercourse. Treatment of vaginismus often includes both psychological and behavioral techniques, including

3348-422: Is known under different ancient Latin names for a variety of sexual activities, but usually denotes penile–vaginal penetration. This is often called vaginal intercourse or vaginal sex. Vaginal sex, and less often vaginal intercourse , may also denote any vaginal sexual activity, particularly if penetrative , including sexual activity between lesbian couples . Copulation , by contrast, more often denotes

3441-568: Is less risky than vaginal or anal intercourse. Many times, STIs initially do not cause symptoms, increasing the risk of unknowingly passing the infection on to a sex partner or others. There are 19 million new cases of sexually transmitted infections every year in the U.S., and, in 2005, the World Health Organization (WHO) estimated that 448 million people aged 15–49 were infected per year with curable STIs (such as syphilis , gonorrhea and chlamydia ). Some STIs can cause

3534-637: Is often based on penile–vaginal intercourse is because heterosexual couples may engage in anal or oral sex as a way of being sexually active while maintaining that they are virgins since they have not engaged in the reproductive act of coitus. Some gay men consider frot or oral sex as a way of maintaining their virginities, with penile-anal penetration used as sexual intercourse and for virginity loss, while other gay men may consider frot or oral sex as their main forms of sexual activity. Lesbians may categorize oral sex or fingering as sexual intercourse and subsequently an act of virginity loss, or tribadism as

3627-492: Is often extra-marital; the study considered the Indian subcontinent to also fall into this group, though data was only available from Nepal . In the second group, the data indicated families encouraged daughters to delay marriage, and to abstain from sexual activity before that time. However, sons are encouraged to gain experience with older women or prostitutes before marriage. Age of men at sexual initiation in these societies

3720-409: Is possible at any time of the menstrual cycle for women. Sex pheromones facilitate copulatory reflexes in various organisms, but, in humans , the detection of pheromones is impaired and they have only residual effects. Non-primate females put themselves in the crucial lordosis position and remain motionless, but these motor copulatory reflexes are no longer functional in women. During coitus,

3813-453: Is possible that individuals who engage in oral sex, but do not consider it as 'sex', may not associate the acts with the potential health risks they can bring." In other cases, condom use is a factor, with some men stating that sexual activity involving the protection of a condom is not "real sex" or "the real thing". This view is common among men in Africa, where sexual activity involving

3906-451: Is significantly less research on behaviors with regard to condom use for anal and oral sex. The most effective way to avoid sexually transmitted infections is to abstain from sexual intercourse, especially vaginal, anal, and oral sexual intercourse. Decisions and options concerning birth control can be affected by cultural reasons, such as religion, gender roles or folklore . In the predominantly Catholic countries Ireland, Italy, and

3999-603: Is usually thought that individuals who make a pact also promise to demons that they will kill children or consecrate them to the devil at the moment of birth (many midwives were accused of this, due to the number of children who died at birth in the Middle Ages and the Renaissance ), take part in Witches' Sabbaths , have sexual relations with demons, and sometimes engender children from a succubus , or an incubus in

4092-453: Is very difficult" and that this is "because most sexually active individuals practice oral sex in addition to other forms of sex, such as vaginal or anal sex, when transmission occurs, it is difficult to determine whether it occurred as a result of oral sex or other more risky sexual activities". They added that "several co-factors may increase the risk of HIV transmission through oral sex"; this includes ulcers, bleeding gums , genital sores, and

4185-837: 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

4278-407: 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

4371-736: 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

4464-468: 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

This edition is notably longer, with more chapters, examples and it includes an appendix with an exorcism. The book was not translated into English until 1929, when this was accomplished under the direction of the eccentric witchcraft scholar Montague Summers . This article about

An example of this is the Nazi-Jewish negotiations during The Holocaust , both positively and negatively. Under Jewish law, the principle of pikuach nefesh ("saving life") is an obligation to compromise one's principles in order to preserve human life. Rudolf Kastner

4743-487: 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

4836-793: 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

4929-637: 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

5022-463: The West. In the 10th century, the poet nun Hroswitha of Gandersheim adapted the text of Paulus Diaconus for a narrative poem that elaborates Theophilus' essential goodness and internalizes the seduction of good and evil, in which the devil is magus , a necromancer . As in her model, Theophilus receives back his contract from the devil, displays it to the congregation, and soon dies. A long poem on

5115-456: 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

5208-405: 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

5301-608: 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

5394-438: The case of women. The pact can be either oral or written. An oral pact may be made by means of invocations , conjurations , or rituals to attract the demon; once the conjure thinks the demon is present, they ask for the wanted favour and offer their soul in exchange, and no evidence is left of the pact. But according to some witch trials , an oral pact left evidence in the form of the Witches' mark , an indelible mark where

A number of famous works refer to pacts with the devil, from the numerous European Devil's Bridges to the violin virtuosity of Giuseppe Tartini and Niccolò Paganini to the "crossroad" myth associated with Robert Johnson . In Stith Thompson 's Motif-Index of Folk-Literature , "Bargain with the devil" constitutes motif number M210 and "Man sells soul to devil" motif number M211. It

5580-468: The demons, usually Satan. According to demonology , there is a specific month, day of the week, and hour to call each demon, so the invocation for a pact has to be done at the right time. Also, as each demon has a specific function, a certain demon is invoked depending on what the conjurer is going to ask. In the narrative of the Synoptic Gospels , Jesus is offered a series of bargains by

5673-485: 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

His story appears in a Greek version of the 6th century written by a " Eutychianus " who claims to have been a member of the household in question. A 9th-century Miraculum Sancte Marie de Theophilo penitente inserts a Virgin as intermediary with diabolus , his "patron", providing the prototype of a closely linked series in the Latin literature of

6138-510: 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

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

6510-431: 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

6603-448: 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

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

6789-645: 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.
