Maybe. But I suspect that men still cheat more ;)
At least in those more traditional societies.
Maybe, I don't know, never gone that route and don't plan on it.
Well, then it must be a quite original theory :) What does it say?
Btw, it's not "my" theory. It's a scientific/psychological/behavioral theory or something. Heard about it many times.
Oh boy, I'm just gonna stir things up now. lol
Well, as you pointed out the theory we all have heard so many times is that males are polygamic by nature to increase the likelyhood of fathering their offspring.
It's been a few years now but in one of our biology classes when human procreation was being discussed several theories were brought up on male versus female traits and behaviors. They were just theories but they all are theories - including the one you brought up. Anyways, one of the things our teacher, who was also a researcher talked about was how males are "quick to the point" while females are slow to warm up but once they do they can go on and on for ever and many are even multi-orgasmic. You know the rocket engine versus the diesel engine theory. In her view that behavior didn't support the "male spreading his seed" theory.
She said that nature does things for a reason and one theory was that females stay aroused for a much longer period because they were meant to mate with several males in order to increase the likelyhood of getting pregnant.
Maybe she was looking for an official excuse to fool around :) I don't know but the "theory" she brought up was as logical as the one you brought up.
She was a little bit of a femi-nazi so maybe her views were slightly skewed because of it BUT I don't think there's a simple explanation to it all.
PS. The link in pgtx's post # 509 seems to support the theory we were told about.
