Vaginal orgasm

The female body can achieve orgasm from stimulation of the clitoris and from stimulation of the G-spot. The Grefenberg spot, or G-spot, is a small area behind the female pubic bone surrounding the urethra and accessible through the anterior wall of the vagina. Many scientists believe that only certain women possess a G-spot. The G-spot orgasm is sometimes referred to as "vaginal," because it results from stimulation inside the vagina, including during sexual intercourse. However, only stimulation of the G-spot, and not other intra vaginal stimulation, results in a "vaginal orgasm."

The "two-orgasm theory" (the belief that in women there is a vaginal orgasm and a clitoral orgasm), has been criticized by feminists such as Ellen Ross and Rayna Rapp as a "transparently male perception of the female body".[5] The concept of purely vaginal orgasm was first postulated by Sigmund Freud. In 1905, Freud argued that clitoral orgasm was an adolescent phenomenon, and upon reaching puberty the proper response of mature women changes to vaginal orgasms. While Freud provided no evidence for this basic assumption, the consequences of the theory were greatly elaborated, partly because many women felt inadequate when they could not achieve orgasm via vaginal intercourse that involved little or no clitoral stimulation.

In 1966, Masters and Johnson published pivotal research about the phases of sexual stimulation. Their work included women and men, and unlike Alfred Kinsey earlier (in 1948 and 1953), tried to determine the physiological stages before and after orgasm. One of the results was the promotion of the idea that vaginal and clitoral orgasms follow the same stages of physical response. Masters and Johnson also argued that clitoral stimulation is the primary source of orgasms.

Recent discoveries about the size of the clitoris - it extends inside the body, around the vagina[7] - complicate or may invalidate attempts to distinguish clitoral vs. vaginal orgasms. Recent anatomical research shows that there are nerves connecting intra vaginal tissues and the clitoris.[citation needed] This, with the anatomical evidence that the internal part of the clitoris is a much larger organ than previously thought, could explain credible reports of orgasms in women who have undergone clitorectomy as part of female circumcision. The link between the clitoris and the vagina is evidence that the clitoris is the 'seat' of the female orgasm and is far more wide-spread than the visible part most people associate with it. But it is possible that some women have more extensive clitoral tissues and nerves than others, and so that some women can achieve orgasm only by direct stimulation of the external part of the clitoris.
