While men tend much more to be interested in casual sex than women, research shows that women are much picker in choosing men when they do decide to engage in casual sex.
Dr Schützwohl and his colleagues looked at the influence of an imagined requestor's physical attractiveness on men's and women's willingness to accept three distinct offers: go out, go to their apartment and go to bed with them. A total of 427 male and 433 female students from the US, Germany and Italy answered a questionnaire. They were asked to imagine being approached by a member of the opposite sex, described as either "slightly unattractive", "moderately attractive" or "exceptionally attractive". They then rated how likely they would be to accept each of the three offers (Springer Science+Business Media, 2009)
The intention of the experiment was thus not only to compare behavioral tendencies of men and women when it came to engaging in casual sex, but to compare and contrast sexual norms of different cultures. Men, of course, across the board, were more likely to accept an offer for casual sex than women were. German men, however, were less likely to accept such a request than either Americans or Italians. Italian men were at the opposite end of the spectrum, more willing than either German or American men to accept such offers.
For each of the three offers, men were more likely to accept when the hypothetical woman was moderately or exceptionally attractive than when she was slightly unattractive, but whether she was moderately or exceptionally attractive made no difference. Women however placed more importance on the requestor's good looks. They were more likely to accept the apartment and bed requests from an exceptionally attractive man than from either a moderately attractive or slightly unattractive man.
The authors conclude: "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" (Springer Science+Business Media, 2009)
