@DashDynamic,
In the BDSM community there is a small but devout group of white top males who go for black submissive females. The group of white submissive females who go for black tops is much bigger though.
Outside of BDSM there is a fairly large number of black highly educated and successful females who want an educated and successful mate, and there are not a lot of black guys who fit the bill. My impression is that they can find white guys who do and who want them, but this aint easy either.
Dont get discouraged though, go try to get what you want.
