About how people can have sex with a race they otherwise look down on. Even though it may have focused on the whole thing with the penis; (basically "superhumanization bias", where black men are exaggerated in strength and libido; that's why we're to be feared, and even killed if necessary), what I've heard it is really from, is because rather than blacks being oversexualised; it was whites being undersexualized, especially given the religious background, where it was repressed. So sex for them was probably more mechanical (at one point, the Church taught it was only for childbirth; and even then it was suspect), and totally focused on the man anyway. So black men are more into fawning over the woman, telling her she "looks good", touching all over, etc. and they tend to like more body mass, where their own men shame them for that. So that is what made black men appealing to alot of white women (who had never experienced that kind of affection before). But otherwise, they are still these not totally human creatures!
