Want to keep your girlfriend happy in the bedroom? It may be less to do with technique and more to do with how much your family earns.
That’s the findings from a recent study that looked at whether orgasm intensity, frequency and sexual satisfaction are determined by a woman's choice of partner.
The study discovered that frequency was related to intensity, which in turn was stronger when the partner was funny, self-confident and their family were high earners.
The study was carried out by psychologist George Gallup and his colleagues at the University at Albany.
They surveyed heterosexual female college students in relationships about how often they experienced orgasm during sex.
VAGINAL ORGASMS DO NOT EXIST, CLAIMS SCIENTISTS
Women have often declared they can either orgasm through sex or foreplay, but recent research suggests this is wrong.
The study claims there is no such thing as a vaginal orgasm, a clitoral orgasm or even a G-spot.
Instead, the umbrella term 'female orgasm' should be used, the study authors argue.
The experts from the Italian Centre of Sexology maintain that like 'male orgasm', 'female orgasm' is the correct term.
Historically, it was believed that women could orgasm through penetrative sex, and that G-spot, vaginal or clitoral orgasms were all different types of orgasm.
But writing in the journal Clinical Anatomy, the authors said the majority of women worldwide do not have orgasms during penetrative sex.
As a result, women have been labelled with sexual problems that are based on something that doesn’t exist: the vaginal orgasm.
Orgasm intensity was related to how attracted the women were to their partners, how many times they had sex per week, and ratings of sexual satisfaction.
Those with partners who their friends rated as more attractive also tended to have more intense orgasms.
Orgasm frequency was highly correlated with orgasm intensity, and orgasm intensity was a 'marginally better predictor of sexual satisfaction than orgasm frequency', said Professor Gallup.
Sexual satisfaction was also related to how physically attracted women were to their partner, as well as the breadth of his shoulders.
The women who began having sexual intercourse at earlier ages had more sex partners, experienced more orgasms, and were more sexually satisfied with their partners.
‘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 partner,’ added the researchers.
