"Three hundred twenty-three women reported in an online survey their past month frequency of various sexual behaviors (including PVI- penis in vagina intercourse-, vaginal orgasm, and clitoral orgasm), the effects of a longer than average penis on likelihood of orgasm from PVI, and the importance they attributed to PVI and to noncoital sex.
RESULTS: Likelihood of orgasm with a longer penis was related to greater vaginal orgasm frequency... In binary logistic regression, likelihood of orgasm with a longer penis was related to greater importance attributed to PVI.
CONCLUSIONS: Women who prefer deeper penile-vaginal stimulation are more likely to have vaginal orgasm, consistent with vaginal orgasm evolving as part of a female mate choice system favoring somewhat larger than average penises."
