Let the Right One (book & film) featured a vampire girl and a human boy. It's not so much a romance, although the boy does have a crush on the girl. It's more about the friendship though.
Beautiful film, I think they're making an American remake of it.
True Blood has lots of gay/lesbian vampires. The two main vampire chicks on the show are lesbians (Pam & The Queen), the King is gay, and Eric Northman has swung both ways. A couple episodes back they had Pam going down on a human girl. Not something you see often on TV, let alone a TV show about vampires.![]()
