Engraçado, eu já li por aí que existiam orgasmo vaginal e clitoriano… Depois do que você falou eu dei uma olhada no site da Wikipedia e veja o que eu encontrei:
Vaginal versus clitoral orgasmsA distinction is sometimes made between clitoral and vaginal orgasms in women. An orgasm that results from combined clitoral and vaginal stimulation is called a blended orgasm. Many doctors have claimed that vaginal orgasms do not exist and that female orgasms are obtained only from clitoral arousal. Recent discoveries about the size of the clitoris - it extends inside the body, around the vagina[21] - complicate or may invalidate attempts to distinguish clitoral vs. vaginal orgasms.
The concept of the purely vaginal orgasm was first promulgated 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 to support this basic assumption, the consequences of the theory were greatly elaborated thereafter, not least because many women felt inadequate when they could not achieve orgasm via vaginal intercourse that involved little or no clitoral stimulation. Freud's theories on this, and indeed many other biological subjects, were later largely proven false or based on supposition.
In 1966, Masters and Johnson published pivotal research into the phases of sexual stimulation. Their work included women as well as men, and unlike Kinsey previously (in 1948 and 1953), set out to determine the physiological stages leading up to and following orgasm.[22] One of the results was the promotion of the idea that vaginal and clitoral orgasms follow the same stages of physical response. Additionally, Masters and Johnson argued that clitoral stimulation is the primary source of orgasms.
A new understanding of the "vaginal" orgasm has been emerging since the 1980s. Many women report that some form of vaginal stimulation in concert with clitoral stimulation is essential to experiencing a fully satisfactory orgasm[citation needed]. Recent anatomical research has pointed towards a connection between intravaginal tissues and the clitoris -- it has been shown that these tissues have connecting nerves. This information, combined 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 so-called female circumcision (also called female genital mutilation). The discovery of the biological link between the clitoris and the vagina lends further credence to the belief that the clitoris is the 'seat' of the female orgasm and indicates that the clitoris is simply far wider-spread than the visible part most people commonly associate with it. It is possible, however, that some women have more extensive clitoral tissues and nerves than others, meaning that some women can achieve orgasm solely via direct stimulation of the external portions of the clitoris.
http://en.wikipedia.org/wiki/Orgasm#Vaginal_versus_clitoral_orgasmsOu seja, na verdade existe só o orgasmo clitoriano, mas os nervos do clitóris estão bem espalhados pela vagina. Os orgasmos "vaginais" nada mais são do que orgasmos via a parte mais externa e invisível do clitóris.
