I've never read 야오이 mangas but i've seen 망가 이미지 that might sound good. I only know two though. Junjou Romantica Sekai Ichi Hatsukoi. They are both from the same writer. I dunno if 당신 want hardcore 또는 soft 야오이 but that's all I really know.
i suggest 당신 read 망가 created 의해 sakuraga mei if 당신 haven't already read it. they're really good, the art, all bishounen and all. and maybe read some stories created 의해 minami haruka. there are some cute characters in her manga. and of course there's those really 인기 anime, which i'm sure 당신 must've watched already, and i really like this anime,kuroko no basuke, although its not yaoi, but there are lots of 야오이 fanfics on this anime.
