Oh my, Junjou Romantica's amazing. I haven't finished the series... But I love it. <3 -Akihiko x Misaki fangirl squeal-
... Anyhow, if you're looking for a yaoi, there is one I've heard about but never seen.
It's called Gravitation! I know nothing about it except the name, but I have seen clips of it, and it looks pretty good...
I hope I helped you! :3
