Well, the only non-heteronormative black gay fiction that I've read all fell under the erotic fiction category. They were usually about a gay guy who was supposedly straight until he started noticing guys for the first time. So I guess from the "Top Whore" perspective.
There was also a mystery/thriller novel that I reviewed for the site years ago called The Messiah.
