amount of Yaoi Manga if enormous. Du should specify what kind Du like to read, in order not to be disturbed oder bored oder waste your time otherwise...
I've never read Yaoi mangas but i've seen Manga Bilder that might sound good. I only know two though. Junjou Romantica Sekai Ichi Hatsukoi. They are both from the same writer. I dunno if Du want hardcore oder soft Yaoi but that's all I really know.
i suggest Du read Manga created Von sakuraga mei if Du haven't already read it. they're really good, the art, all bishounen and all. and maybe read some stories created Von minami haruka. there are some cute characters in her manga. and of course there's those really beliebt anime, which i'm sure Du must've watched already, and i really like this anime,kuroko no basuke, although its not yaoi, but there are lots of Yaoi fanfics on this anime.
