That whole argument...

Why are women who sleep around sluts and whores, but men who sleep around brag about it?

Well, first you have to ask yourself what the primary motivation for sleeping around is.  And guess what, all you modern "feminists" out there, it's not what you've been peddled in your Gender Studies class.

The trouble isn’t men, of course. Nor is it the culture. The trouble is that these women have been sold a lie. They’ve been told that the profound sexual and behavioural differences between men and women are merely matters of individual preference, which would largely dissolve if we ever managed to shed our noxious cultural baggage.
Nothing could be further from the truth, of course.
