There is, actually, a theory that the reason women find it harder to orgasm than men is that they're not evolved for just one partner; evolution designed them to orgasm after the third or fourth fucking.
the prevailing theory is that a girl who had too much pleasure from sex would impregnate too often, therby putting her and her children's life in harm's way given her vulnerability during the gestation. this is why the clitoris is outside the vagina

One of the biggest fallacies in pop evolution is that there is one "best" genotype. The world doesn't stay the same, and no Alpha Male is perfect for everything. In Selfish Gene terms it's actually a better strategy for a female to breed with several different males, so that whatever qualities happen to be most useful to the next generation - strength, speed, cunning, a good thick coat - at least one set of her genes will be paired with that.
i beg to differ. strength, speed, and physical fitness are good in any climate- this is why women prefer a higher shoulder to hip ratio. furthermore, being intelligent is a nonissue. http://www.amazon.com/gp/product/038...SIN=0385342160 there is no time where a woman will leave a fit, healthy man for a fat man just because it gets cold. the reverse would be true, she has limited eggs and doesn't want to waste them with duds. this is why humans have less genetic diversity than other mammals though we have more numbers. there is a certain set of traits that all females from nearly every culture finds attractive, things like syymetry, distance between eyes relative facial width and so on. and to hammer it home, we are descended from 2 to 3 times more females than males, so the genetic winners amongst the y chromosomes were a select few, not women breeding with a diverse group of men
