Have you ever read bishlov's "Yukito's Little Secret" where Yukito wonders if his relationship with Touya might be easier if he (Yukito) were a girl, and then voila! She had it on ff.net before TPTB took it down for no apparent reason, so it's on mm.org (http://www.mediaminer.org/fanfic/view_ch.php?cid=94797&submit=View+Chapter&id=35028) now.
