Women Achieve More Orgasms With Attractive Partners
Female orgasms serve an evolutionary purpose: they increase fertility by increasing the retention of sperm.
A new paper, in press at Evolution and Human Behavior, examines the timing and frequency of female orgasms and finds evidence that on average, women have orgasms before men, and that most frequently they involve some activity other than intercourse.
Not the kind of information that soothes the male ego.
The orgasm frequency found among the participants in their study is as follows:
The researchers found that if the man in the couple is very attractive and/or very masculine, the woman is significantly more likely to have an orgasm either at the same time as her partner, or just after. So the timing of orgasms for women with attractive partners coincides with the period that increases fertility.
This supports the argument that orgasms play an evolutionary function - women orgasm more frequently and with better timing when their partners have better genes.
