Journalist Daniel Bergner explains in this video, 99% of What We Believe About Female Sexuality is Nonsense, that there is a common misconception about the sexuality of the genders:
the idea that while men are genetically programmed to spread their limitless seed and be promiscuous that women by contrast are genetically programmed, evolutionary scripted to seek out one good man, seek out one good provider, seek out closeness and constancy and so that at least relatively speaking by this theory women are somewhat better suited to monogamy, have a sex drive that’s a bit less raw, a bit less animalistic than male libido.
He argues against this proposition, by referring to a study where women's stated subjective sexual responses to erotic scenarios didn't match the objective measurement of blood flow to their genitals - in particular, they were more aroused by the idea of sex with strangers over sex with close friends than they admitted.
By itself, this isn't sufficient to overthrow the more common understanding.
Is there evidence that men are/are not genetically programmed to seek multiple sexual partners more so than women?
