Sorry, het only. (Though feel free to post it if it has any focus on a het pairing--it doesn't have to be the main focus. Or if the fic can be deemed "het" without necessarily being overtly romantic, that's fine, too--i.e. a fic focusing on the relationship between Neville and Hermione would be okay, even if it's not necessarily romantic in nature.) You could probably post your fic to character-specific asylums (assuming there are some for the characters in your fic). I don't know of a gen asylum. (Though if you find one, I'd love to know about it!)
