Casual sex, one night stands: men vs women, Germans vs Americans

Yes, people actually research things like "How willing are you to accept sexual requests from slightly unattractive to exceptionally attractive imagined requestors?" Dr Achim Schützwohl et al, Brunel University (2009).

From the press release 11 August 2009:

Only the best looking men tempt women into casual sex

Men are far more interested in casual sex than women. While men need to be exceptionally attractive to tempt women to consider casual sex, men are far less choosy…

…men are more likely than women to report having had casual sex and they express a greater desire for it than do women. It is also thought that women but not men raise their standards of attractiveness for a casual sex partner.

As well as gender differences there were differences by culture / nationality / country:

The requestor's looks affected men and women differently. Across all three levels of requestor attractiveness, men were more likely to go out, go to their apartment and go to bed with them than were women. German men were less likely to go out with the requestor and go to their apartment than American and Italian men. Italian men were more likely to go to bed with the requestor than were American men. German men were even less likely than American men to go to bed with the requestor. These differences highlight cultural differences in sexual morals and preferences…

While men are not entirely insensitive to their requestor's attractiveness, women have higher standards and are more likely to engage in casual sex with an exceptionally attractive man than with a less attractive man.

So basically women interested in one night stands are more likely to get lucky than men are, especially less good looking men.

Errr, didn't we already know that?!
