The aforementioned Lynn Flewelling and Sarah Monette, Ellen Kushner, Steve Berman. Maureen F. McHugh's China Mountain Zhang. Our hostess, in particular Carnival and the Stratford Man books (Ink and Steel is the first of the two). Hal Duncan, I expect, though I haven't read. Peg Kerr's the Wild Swans. (And I'm sure there are more male names I'm not thinking of.)
Those are ones where the protagonist is gay/bi. Include major supporting characters and I can add authors. If you like romances, there are whole small presses dedicated to them.
That's not a terribly big list. I am aware there's still a way to go in the frequency. But it's a case for me of "Look, that series was a bestseller still in print. How is this not a done question?"
Then something comes along like Rachel Manija Brown and Sherwood Smith being told that their book would be a better sell if they made the gay protag (one of five!) straight. And I facepalm all over again.
