True. No woman that I know about is black only.True. How could anybody make a statement about another person's personal experiences? But also... How could you say to not know any "black only" women? Everybody probably knows a bunch of women but who actually knows each of their sexual past and present exactly? It's not what people usually brag about in their day-to-day lives, at least not to every random person.
But it's circumstances, to some extent. We don't have a lot of blacks where i am. I can think of one woman who would be black only if there were more black guys to choose from.
