 Researchers also looked at their partner's family income, body measurements, personality, and how good looking they were.

Their looks were judged by the woman's friends to give a less biased score.

Findings concluded that orgasm intensity was related to how attracted the women were to their partners, how much sex the couple had per week, and ratings of sexual satisfaction.

Women who have partners whose friends consider him good looking were found to have more intense orgasms.

Other findings said the intensity of orgasms were a marginally better indication of sexual satisfaction than how frequently women experienced them.

 Men with broad shoulders were found to be more likely to have a sexually satisfied partner.

 Women who started having sex at earlier ages had more partners, experienced more orgasms, and were more satisfied in bed with their partners.

Professor Gallup said: "We also identified a [series] of partner psychological traits - motivation, intelligence, focus, and determination - that predicted how often women initiated sexual intercourse.

"Their partner's sense of humour not only predicted his self-confidence and family income, but it also predicted women's propensity to initiate sex, how often they had sex, and it enhanced their orgasm frequency in comparison with other partners."

Other research has found horny women fake orgasms to make sex better and keep their men happy.
