i've read a lot of HP fiction, mostly snarry and so-called snupin (snape/lupin). i got into the fandom because of the hotness of rickman, but it wasn't long until david thewlis revved my engine up REAL high. ;)

but you're so right about Clex's erotic potential. i've never read any other pairing that had so many possibilities. i like lex as top, lex as bottom, lex in drag, lex as damaged victim of abuse, just about any way at all; and there's always a way to tailor clark precisely to him. (i like AU best, really.)
