I never said all men sleep around, I said the opposite, most men (and women) only have a handful of partners, but there's a one person difference in that handful and it's one point to the males. Yes, more women reproduce, but that isn't the same thing as having more partners, or more sex, that's just more overlap of who they sleep with and get pregnant with. subtle difference. There's also the difference between less sex and no sex, marriage and never married. Seems to be less sex and less marriage ultimately, but the virginity thing usually resolves itself in the twenties for both sexes, was it 98% or something? I don't know, can't stand reading this stuff. i understand it's implications are important but but as a religious person everyone is getting upset for the wrong reasons here. Not sleeping around outside of marriage is good for society. A lot of these guys are just mad they can't do what they shouldn't be doing anyways, lot of women too, and that will decrease marriage satisfaction and stability later for both (though that was a different and small study that is often sighted around these discussions).
