Can Someone Please Suggest a Good Yaoi/Shonen-Ai Manga/Anime?

I would absolutely watch Love Stage! It's really sweet, has pretty good characters, and is a lot of fun to watch.

Neon amber sign!

Sekaiichi hatsukoi is definitely one of the best yaoi anime ever made, I highly recommend it!!

Antique Bakery is a personal favourite of mine. Though shounen ai is not the main focus of it, it's still there. Love Stage!! is a great one too~ Have watched it many times and love the manga too.
