Some I've read, and what I'm looking for:
Hua Hua You Long (Kind of graphic but it doesn't matter... 😐 )
Koi Shika Dekinaiyo
Sweet Chapel (Shounen ai but one of my all time favorites)
Crimson Spell
(I've read Kawaii Akuma. No growth spurt please 🙂 )

Please don't suggest a manga with buff people, like Bousou Kareshi

And no Koisuru Boukun. I prefer the uke with shot hair (and maybe seme with long) unless they both have it long like Hua Hua You Long

Thank you!

April 4th - it has seme who is very feminine looking (to the point of mistaking him with a girl, and he does modeling thanks to his not manly facial features) and has long hair.

105 Goushitsuji no Inu they haven't had sex yet but it's kinda obvious who's gunna be the seme
Ubawareru Koto Marugoto Zenbu
Love Neco
Akiyama-kun The uke is very cool and macho while the seme is a crybaby
