Roissy is disgusting. I'd rather be celibate than be him. Hell, I'd rather be a lot of things than be him, and that includes myself! ;)

And, AFAICT, being a "beta" seems to have been a reasonably successful reproductive strategy. The virgin/whore dichotomy applies to men, too; girls might have a short-term affair with the bad boy, but they usually don't marry him. And even if your wife cheats on you once in a while, you're still likely to end up with some biological children of your own anyway.
