Have you read it yet?! Have you?! Its completely hot, isn't it? ヾ(☆▽☆) OMG I READ IT AGAIN AND MY EARS BURST INTO FLAMES!
I think that them being seke would be way better than assigning them uke and seme roles. Because, lets face it, switching is really sexy. And they have the same build, and none of them are weak or look weak, and WOW. Gosh, I'd make a dj of 19 days with pure sex if I were that good at drawing.
Its your first yuri, huh? Yuri mangas are kinda weird because either the story turns out to be disappointing or the art becomes terrible. But, if kawaii yuri is your thing (it certainly is mine), give Exciting Feelings a try.
Koimonogatari! I've been eagerly waiting for its update! One of those rare mangas with actual character development! <3 I love it sooo much!
I've read the other manga you suggested to me(the love letter one). Its a new concept, and I love it. So kawaii!
