Ok so it's a bit of a long shot but I'm looking for a yaoi/shounen ai manga about a guy who gets into a relationship with another guy and the other guy is always saying how he likes his voice {which is girly}
But then the guy's voice breaks and, well some kind of drama ensues.

I know I've read something like this before. It was possibly this one: Kaze ni Chiru Hanabira to Kisu which I just saw in a forum but I'm not 100% sure.

Anyways, I hope you guys know about other ones.
No tragedy please.

maybe Aishi no Sweet Voice and Sexy Cool Voice

I have the simplest tastes. I am always satisfied with the best.

Thanks very much for the recommendations, it's funny you should recommend Aishi no sweet voice because that was the manga that made me think about the topic. I haven't finished it yet though and Sexy cool voice will definitely be next.
