my favourite yaoi manga, just anything by this mangaka is fluffy and cute.
Also anything by Yamamoto Kotetsuko is so great and fluffy, and their characters are always so cute and handsome, same with Kanda Neko!!! Hope you enjoy!! :D
I would recommend Ichikawa Kei's and Natsume Isaku's works.
Also these:

I started reading yaoi like few months ago... lol before I was curious why people read this genre, and now I understand why... at first I felt really uncomfortable like why are they like connecting that part to that part, haha well my first yaoi manga was 'yatamomo' it was so intense for a beginner. but overall i like it at the end LOL ... and um...lastly, i wanna ask u guys if u have any fav fluffy yaoi mangas to recommend?(≧∀≦)
