I like the romance, too, and the desire. When the sex is just body parts, it's no fun for me...it's got to be mixed in with issues of desire, personality, and, sometimes, power, for it to be interesting and compelling.

Romance novels have desire, but it's usually so cliched. Good slash fanfic is constantly trying to write desire in new, fresh ways. The whole subversiveness of same-sex pairings helps with that, of course.
