Orgasms: Facts, types, causes, and misconceptions

It is very technical. Good compilation of all the research on orgasm. I like the last chapter when it speculate about consciousness and its relation to orgasm. Nov 17, Art rated it it was amazing. Highly technical, but quite readable, gives the reader a wonderful understanding of what is happening in the human body leading up to and at the point of orgasm. Jun 02, Laura Szumowski marked it as to-read. Excellent so far, very well researched.

During the study, six fully ejaculatory orgasms were experienced in 36 minutes, with no apparent refractory period. In women, the most common way to achieve orgasm is by direct sexual stimulation of the clitoris meaning consistent manual , oral or other concentrated friction against the external parts of the clitoris. One misconception, particularly in older research publications, is that the vagina is completely insensitive.

Sex educator Rebecca Chalker states that only one part of the clitoris, the urethral sponge, is in contact with the penis, fingers, or a dildo in the vagina. 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 restimulated before tensions have dropped below plateau phase response levels". 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 , 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 the central component to women's sexual satisfaction.

The first major national surveys of sexual behavior were the Kinsey Reports. 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. Accounts that the vagina is capable of producing orgasms continue to be subject to debate because, in addition to 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.

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 the same stages of physical response. On this basis, they argued that clitoral stimulation is the source of both kinds of orgasms, [59] [60] 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 research additionally indicates a connection between orgasms experienced vaginally and the clitoris, suggesting that clitoral tissue extends into the anterior wall of the vagina and that therefore clitoral and vaginal orgasms are of the same origin. 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 the bulbs of the clitoris—triangular, crescental masses of erectile tissue.

In , they published the first complete 3D sonography of the stimulated clitoris, and republished it in 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 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. It's a region, it's a convergence of many different structures. Regular difficulty reaching orgasm after ample sexual stimulation, known as anorgasmia , is significantly more common in women than in men see below.

Scholars state "many couples are locked into the idea that orgasms should be achieved only through intercourse [vaginal sex]" and that "[e]ven 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 ". In the first large-scale empirical study worldwide to link specific practices with orgasm, reported in the Journal of Sex Research in , demographic and sexual history variables were comparatively weakly associated with orgasm.

Data was analyzed from the Australian Study of Health and Relationships, a national telephone survey of sexual behavior and attitudes and sexual health knowledge carried out in —, with a representative sample of 19, Australians aged 16 to Generally, 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 book Sexual Behavior in the Human Female , stated that exercise could bring about sexual pleasure, including orgasm. In both sexes, pleasure can be derived from the nerve endings around the anus and the anus itself, such as during anal sex. It is possible for men to achieve orgasms through prostate stimulation alone.

It is also typical for a man to not reach orgasm as a receptive partner solely from anal sex. For women, penile-anal penetration may also indirectly stimulate the clitoris by the shared sensory nerves, especially the pudendal nerve , which gives off the inferior anal nerves and divides into the perineal nerve and the dorsal nerve of the clitoris. The aforementioned orgasms are sometimes referred to as anal orgasms, [86] [87] 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 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. An orgasm is believed to occur in part because of the hormone oxytocin , which is produced in the body during sexual excitement and arousal and labor. It has also been shown that oxytocin is produced when a man or woman's nipples are stimulated and become erect.

Masters and Johnson were some of the first researchers to study the sexual response cycle in the early s, based on the observation of women and 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 the blood leaves the genitals.

In the s, 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. Rather than orgasm being the peak of the sexual experience, she suggested that it is just one point in the circle and that people could feel sexually satisfied at any stage, reducing the focus on climax as an end-goal of all sexual activity. As a man nears orgasm during stimulation of the penis, he feels an intense and highly pleasurable pulsating sensation of neuromuscular euphoria.

These pulses are a series of throbbing sensations of the bulbospongiosus muscles that begin in the anal sphincter and travel to the tip of the penis.

The science behind how men and women orgasm differently

They eventually increase in speed and intensity as the orgasm approaches, until a final "plateau" the orgasmic pleasure sustained for several seconds. During orgasm, a human male experiences rapid, rhythmic contractions of the anal sphincter , the prostate, and the muscles of the penis. The sperm are transmitted up the vas deferens from the testicles , into the prostate gland as well as through the seminal vesicles to produce what is known as semen. 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 a pleasurable feeling.

The search for the multiple orgasm - does it really exist?

It is believed that the exact feeling of "orgasm" varies from one man to another. This does not normally affect the intensity of pleasure, but merely shortens the duration. 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. A woman's orgasm may last slightly longer or much longer than a man's. In some instances, the series of regular contractions is followed by a few additional contractions or shudders at irregular intervals.

Women's orgasms are preceded by 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, 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.
