Researchers in Britain have carried out the study and found that women's sexual pleasure is directly linked to their partner's bank balance -- in fact, the wealthier a man is, the more frequently his ladylove has orgasms.

"Women's orgasm frequency increases with the income of their partner," lead researcher Thomas Pollet of the Newcastle University was quoted by 'The Sunday Times' as saying.

The researchers came to the conclusion after analyzing data gathered in one of the world's biggest lifestyle studies, the Chinese Health and Family Life Survey which targeted 5,000 people for in-depth interviews about their sex lives, income.

Among these were 1,534 women with male partners whose data was the basis for the study.

They found that 121 of these women always had orgasms during sex, while 408 more had them "often". Another 762 women ‘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 money was one of the main ones, according to the researchers.

Pollet 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."
