“Women’s orgasm frequency increases with the income of their partner,” said Dr Thomas Pollet, the Newcastle University psychologist behind the research.
The expert reckons the phenomenon is an “evolutionary adaptation” that is hard-wired into women, driving them to select men on the basis of their perceived quality, reports a major news website.
The idea behind the study of Pollet, and Professor Daniel Nettle, his co-author, is that the female orgasm is an evolutionary adaptation that drives women to choose and retain high-quality partners.
To test the belief, the experts used data gathered in one of the world’s biggest lifestyle studies. The Chinese Health and Family Life Survey targeted 5,000 people across China for in-depth interviews about their personal lives, including questions about their sex lives, income and other factors. Among these were 1,534 women with male partners whose data was the basis for the study.
From the analysis, they found that 121 of these women always had orgasms during sex, while 408 more had them “often”. Another 762 “sometimes” orgasmed while 243 had them rarely or never. Such figures are similar to those for western countries.
There were of course, several factors involved in such differences but, said Pollet, money was one of the main ones.
He said: “Increasing partner income had a highly positive effect on women’s self-reported frequency of orgasm. More desirable mates cause women to experience more orgasms.”
