An investigation of selected traditional assumptions about sexual arousal, orgasm and pleasure
Abstract
Relatively few studies have been conducted on orgasm, and several traditional assumptions about its relationship to sexual arousal and pleasure have not been empirically confirmed. The majority of orgasm research has focused on orgasmic difficulties in women. Following a review of our current understanding of orgasm and female orgasmic disorder (presented in Manuscript One), this research aimed to test the following assumptions: (a) clitoral stimulation is very important to women's ability to reach orgasm, (b) sexual arousal (and possibly orgasm) decreases genital pain sensitivity and increases pleasurable sensitivity, (c) men's sexual arousal decreases more consistently after orgasm than women's, and (d) orgasms are more pleasurable following a greater build-up of sexual arousal. In Manuscript Two, the literature on female genital mutilation/cutting and surgical restoration of the external clitoris was reviewed, and found to indirectly support the first assumption. Two experimental studies were conducted to investigate changes in sensitivity and sexual arousal/desire, respectively, with masturbation to orgasm in the laboratory. As described in Manuscript Three, the results of the first study contradicted the second assumption: women's genital pain sensitivity increased rather than decreased following masturbation (on the vulvar vestibule, especially with masturbation to orgasm), and pleasurable sensitivity did not change from baseline. As described in Manuscript Four, the…
