The Specificity of Women's Sexual Response and Its Relationship with Sexual Orientations: A Review and Ten Hypotheses.

Category-specific sexual response describes a pattern wherein the individual shows significantly greater responses to preferred versus nonpreferred categories of sexual stimuli; this pattern is described as gender specific for sexual orientation to gender, or gender nonspecific if lacking response differentiation by gender cues. Research on the gender specificity of women's sexual response has consistently produced sexual orientation effects, such that androphilic women (sexually attracted to adult males) typically show gender-nonspecific patterns of genital response and gynephilic women (sexually attracted to adult females) show more gender-specific responses. As research on the category specificity of sexual response has grown, this pattern has also been observed for other measures of sexual response. In this review, I use the Incentive Motivation and Information Processing Models as complementary frameworks to organize the empirical literature examining the gender specificity of women's sexual response at each stage of sexual stimulus processing and response. Collectively, these data disconfirm models of sexual orientation that equate androphilic women's sexual attractions with their sexual responses to sexual stimuli. I then discuss 10 hypotheses that might explain variability in the specificity of sexual response among androphilic and gynephilic women, and conclude with recommendations for future research on the (non)specificity of sexual response.
