“…Congruent with the view that vaginal orgasm has an adaptive role of reinforcing desire for PVI, vaginal orgasm and PVI frequency are consistently associated with sexual satisfaction, relationship satisfaction, greater sexual desire and less risk of sexual dysfunction (Brody, 2007b;Brody & Weiss, 2011b;Costa & Brody, 2007;Fugl-Meyer, Oberg, Lundberg, Lewin, & Fugl-Meyer, 2006;Nutter & Condron, 1983;Philippsohn & Hartmann, 2009;Tao & Brody, 2011;Weiss & Brody, 2009a). In contrast, other sexual behaviors are frequently uncorrelated or correlated with more sexual difficulties (Brody & Costa, 2009b;Brody & Weiss, 2011a;Costa & Brody, 2007;Das, Parish, & Laumann, 2009;Gerressu, Mercer, Graham, Wellings, & Johnson, 2008;Lau, Cheng, Wang, & Yang, 2006;Nutter & Condron, 1983;Philippsohn & Hartmann, 2009;Shaeer, Shaeer, & Shaeer, 2012;Tao & Brody, 2011;Weiss & Brody, 2009a). Although Prause ignores this literature in her review concluding that orgasm has no primary role in rewarding women's sexual behavior, her own data seemingly conform to the pattern: women who considered the vagina the most important site for orgasm (when compared to women for whom the clitoris was the most important site for orgasm) had more desire for sex with a partner, but not more desire for masturbation.…”
