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. Of course that would place it way back in the days when we still had a mating season.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.And, to a certain extent, women tend to be attracted to Alpha males, as they would be considered genetically superior, whose children would be likely to survive into adulthood, in order to continue the genetic line.
