amount of Yaoi Manga if enormous. anda should specify what kind anda like to read, in order not to be disturbed atau bored atau waste your time otherwise...
I've never read Yaoi mangas but i've seen Manga imej that might sound good. I only know two though. Junjou Romantica Sekai Ichi Hatsukoi. They are both from the same writer. I dunno if anda want hardcore atau soft Yaoi but that's all I really know.
i suggest anda read Manga created sejak sakuraga mei if anda haven't already read it. they're really good, the art, all bishounen and all. and maybe read some stories created sejak minami haruka. there are some cute characters in her manga. and of course there's those really popular anime, which i'm sure anda 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.
