Maybe you'll find something to your liking here. All of them are over 10 chapters http://www.mangago.zone/home/mangalist/19097/
Don't forget Sekaiichi! (⌒▽⌒)
Not Equal and this; http://www.mangago.zone/read-manga/feng_yu_jiu_tian/ looks really interesting, if you want something out of the typical yaoi... Merry has lots of that variety on her list ╮( ̄▽ ̄)╭
try this list, it doesn't have long stories, on the contrary,most of them are short stories, but they have vry gud plots

Try something from Shoowa her mangas are quite unique.
I'm just really, REALLY tired of reading one-chapter mangas where one male will be "OMG I met you five minutes ago let's go have sex!!!" and the other is like "OMG I've liked you for xx amount of years so I'll say yes!" or "Well, I don't know you, but sure D:" And then its all smut from there. Please help a plot-depraved girl?
Also, I've seen Junjou Romantica(Egoist XD<3)/Okane ga Nai/Loveless/Gravi/whatever other common BL story that everyone knows about. I want something... that's not that common? Please and thank you! ^__^
