I don't know how common it is, but I know that some girls do actually have a preference for black men over white men (as some men prefer chinese girls to white girls). I was wondering why this was? Is it purely physical or something else? In America, black men/white women are 2.5 times more likely to marry than black women/white men. It's the most common racial mix.
Not the sort of question you would ask in public much, but on a forum...
