Free Oral Sex for Every Body: Giving and Receiving for Men and Women by Tina Robbins

whose categorization of female orgasms provokes controversy to this very day. According to Freud, female orgasms are divided into two types: vaginal and clitoral. He considered clitoral orgasms to be a simple “intermediate” stage of pleasure, whereas vaginal orgasm represented a woman’s reaching a “true” climax. One theory which Freud left in the background was the extremely important role the clitoris plays in a full sexual relationship.

    This erroneous idea of two types of orgasm held sway until biologist Alfred Kinsey observed how important the clitoris was to female pleasure. After talking with thousands of women, Kinsey demonstrated that there was no reason to consider coitus as the easiest way to cause a female orgasm.

    Later on, it was Masters and Johnson who emphasized the importance of the clitoris. After observing almost fifteen thousand instances of coitus and masturbation, the researchers
    came to the conclusion that there was just one type of orgasm, regardless of the means by which it was obtained.

    These results were later supported by another prestigious investigator, Shere Hite. In her two reports on female sexuality (published in 1976 and 2000), it was stated that more than 70 percent of women surveyed stated that they did not arrive at orgasm by way of vaginal penetration without simultaneous stimulation of the clitoris.

    THE “G” SPOT

    It had been clear that the “star” of female orgasm was the clitoris. That was until 1950, when a German gynecologist named Ernst Gräfenberg discovered a small erogenous zone located in the vagina behind the pubic bone, near the urethra, about one-and-a-half to two inches (4 to 5 cm) back from the vaginal opening. He had discovered the now famous and controversial “G” spot. He did not delay in demonstrating that its direct stimulation provoked intense erotic excitation and pleasure in a majority of women.

    It was sexologists John Perry and Beverly Whipple who, years later, actually named it the “G” spot, in honor of its discoverer. They concluded that in the vagina there was a place “extremely sensitive to firm pressure,” which under adequate stimulation succeeded in triggering serial orgasms. In addition, Perry and Whipple brought to awareness the existence of female ejaculation and the relationship between the strength of a woman’s pubococcygeus muscle (PC muscle) and her capacity for orgasm.
    They quickly published a book that explained the results of their investigations and rapidly sold out in bookstores all over the world (it was translated into over twenty languages).

    According to these investigators, there are three types of female orgasm:
Clitoral Orgasm. Characterized by involuntary, rhythmic contractions of the pubococcygeus (PC) muscle. Penetration isn’t required; only clitoral stimulation is necessary.
Uterine Orgasm. This takes place as a result of deep penetration. This doesn’t provoke multiple orgasms (as does clitoral orgasm), but the resulting single orgasm is very deep. This type of orgasm is not common.
“Mixed” Orgasm. A combination of the two previous types. It is also know as vaginal orgasm or “G” spot orgasm. It is associated with contractions of the PC muscle characteristic of clitoral orgasm and the deep sensations of uterine orgasm.

    In the case of men, two types of orgasm are described: one produced in the penis and the other in the prostate.

    Since its discovery in the '50s, the “G” spot has been surrounded with controversy. Denied by some and defended by others, it has given rise to much contention among sexologists, doctors, and investigators throughout the whole world.

    The latest revealing data about its existence came about thanks to research done at the University L’Aquila, in Italy.
    In the study, there were nine women who claimed to have experienced vaginal orgasm or “G” spot orgasm, and eleven women who denied having them.
