I would like to know what he means by "The guys they find appealing tend to have characteristics that are attractive in the short term". It sounds like he is saying that women subconsciously are attracted to the guys that they know they wont last in a long term relationship with. Maybe pointing to a scientific explanation of why women more often go to bed with the bad boys that end up using them. But I understand that the bad boys are more comfortable in "flirting" with women than the nice guy who hides his sexual side, so that also may be a factor.
