I’m off to Bristol shortly to do some radio. While I’m away, you might like to take a look at SF Signal where they have a new Mind Meld up: LGBT Themes in Fantasy and SF – Recommendations. There are lots of very splendid people involved. And me.
Reading through the other contributions, I would particularly like to second the mentions of Laurie Marks (from Delia Sherman) and Elizabeth Knox (from Ellen Kushner).
