The reason for white women enjoying black men's aggressiveness sexually is because the white men they are involved with is in the context of a loving relationship where deeper emotional connections lie. They are being used sexually by the black men and treated accordingly, whereas in the context of their union with their white male partners, they are doted on, pampered, respected and even spoiled. They just like the change of pace to have emotion free, animalistic sex and black males provide that because their boyfriends and husbands have deeper and more meaningful feelings for them and therefore cannot (usually) treat them merely as a sexual object most of the time. Just the opposite is true when white males perform sexually with black women in the same context as black men sexually servicing white women. We don't have the same connecting emotion with the black woman so the roles are reversed and we get to unleash our primal sides in that context. And I still say the driving force behind interracial couplings of any kind is the taboo factor. If it wasn't considered naughty or bad not nearly as many people would be engaging in it.
