To date, I haven't commented on this thread because I find the whole female-promiscuity=Bad/Male promiscuity=Human Nature discussion fallacious.
Such labelling says way more about a male's attempt/need to control a female, than anything about her promiscuity (whatever that means).
IMHO, those men concerned about female promiscuity, at the root, are more concerned with their personal insecurity regarding their ability to measure up (pardon the pun) to those that have gone before them.
Honestly, every man somewhere in the back of our mind wants to know (No, I don't...Yes, I do...No, I don't) how we compare to other lovers. We want/need to be, or believe that we are, the woman's "best" lover, ever. That is why there is such a premium on female virginity. "If I'm the first, I have to be her best. And, if I can brow-beat her into believing this promiscuity=Bad thing, I will always be her best."
But it's not about her, it's about our perception of us. If a ["promiscious"] woman told a man that he was her absolute best lover [even if she was lying, and the man didn't know it] and therefore would never leave him, her promiscuity would never be a problem.
So brothas, let's give this, "I'm looking out for the race" thing a rest. Every problem with female promiscuity cited here, has a male somewhere, and equally, involved. Stepping up to this fact is what manhood is about.
