Orgasm is a primitive response of the human body. It is achieved through an identical mechanism regardless of gender and orientation. The key characteristics of orgasm include mental arousal must precede stimulation, stimulation focuses on massaging the blood flow within the corpora cavernosa of the phallus and stimulation ceases once orgasm is achieved.
There is a tendency to focus on physical stimulation techniques when talking about female orgasm. The psychological aspects of arousal are rarely acknowledged. Male arousal may seem automatic. But even men need some kind of mental stimulation, a fantasy or turn-on, to arouse them. Women rarely understand the need for mental arousal, which is often omitted from orgasm claims. It is assumed that women are aroused as men are but this assumption is backed by no evidence (women censor all forms of nudity) and no logic (female arousal is not required for reproduction).
It is often mistakenly assumed that female sexual arousal depends on emotional criteria. This misunderstanding arises for a variety of reasons. First, women tend to associate sexual activity with a loving relationship. Second, many women are uncomfortable with the kind of explicit eroticism that causes arousal. Third, women cannot account for erotic turn-ons.
Orgasm is an instinctive response that involves physical stimulation and mental arousal. Just as men and women (or gays and heterosexuals for that matter) experience responses such as hunger or anger in the same way, so too they must experience orgasm similarly. In the 1950s when the public first learned of female orgasm, there was great excitement that women might be capable of the same sexual response as men. Male orgasm involves a mental focus on eroticism and a rhythmic massaging of the phallus from start to end. Yet female orgasm is associated with emotional factors and a variety of physical stimulation techniques applied to inconsistent anatomy.
There are differences in the orgasm techniques that men and women use. But it is not logical to suggest that a person of one sex achieves orgasm in a different way to another person of the same sex. So, for example, lesbians must use the same orgasm techniques as heterosexual women. This is because our minds and bodies respond in similar ways according to sex. Orientation does not affect responsiveness and how orgasm is achieved.
Female masturbation is associated with lesbians because of the masculine connotations of the clitoris. But responsiveness varies among women, gay and straight, just as it does among men. Gay women do not masturbate any more commonly or more frequently than straight women. The anatomy involved in orgasm must be consistent for women regardless of orientation whether they are alone or with a lover (regardless of their lover’s gender).
We need to contrast the different stimulation men and women obtain from various sexual activities: masturbation alone, oral sex and intercourse. Each of these activities involves penile stimulation for a man. But both the anatomy and the stimulation technique are very different for women.
The phallus (penis or clitoris) is the only erectile organ of the body. Within the phallus are the corpora cavernosa that fill with blood when a person is mentally aroused by stimuli of an erotic nature. This process is almost automatic in young men but requires specific conscious focus for women.
Sexuality includes both conscious behaviours and responsiveness. In terms of reproduction (intercourse replicates the mating act that is so rewarding for the male), a woman has to employ conscious behaviours to complement male responsiveness. But a woman’s enjoyment of her own responsiveness parallels the male experience. This is because the anatomy and mechanism involved in achieving orgasm are the same for everyone. The brain must first respond to erotic stimuli so that blood flows to the erectile organ. Only once the penis or clitoris is tumescent, does orgasm become a possibility.
Kinsey noted that some women masturbate face down and thrust in a way that is typical of male copulatory activity. Women achieved orgasm by emulating the male (not the female) role in intercourse. Once the clitoris was identified as the source of female orgasm, couples were told to include clitoral stimulation in their lovemaking. The clitoris was added as an optional extra and never replaced the vagina. Men still wanted vaginal penetration regardless of female orgasm. But if clitoral stimulation caused female orgasm with a lover, heterosexuals would have discovered the clitoris by themselves. They would not need researchers to tell them about it.
There is no logic to the beliefs people have about how women are believed to achieve orgasm with a lover. We know that these orgasms are fictional because even a man, who is much more responsive, could not orgasm in the ways that are suggested for women. For example, to orgasm from intercourse a woman must orgasm within time constraints set by her lover’s responses of erection and ejaculation. A man cannot orgasm on demand within precise time limits. In addition, no one (certainly not a man) continues the stimulation that caused orgasm once they have had an orgasm.
