I can relate. I don't want to transition either. I mainly don't want to deal with the cost, the nuisance, and don't want to mess with a healthy body. Plus I don't know if I'd be happier living as male. It would be just another label that doesn't have anything to do with who I am.
I'm also a music person. It's a very accepting community to be a part of, and makes it easier to deal with the gender issues (partly because a lot of us have them). But in the long run, I'd like to be respected as a song-writer by people outside of my cozy little scene. Being trans would be too much of a distraction from the music itself. Being female is hard enough - you're a "female guitar player", "female songwriter", etc. If there's something more unusual about you, that's all people see; they stop paying attention to the music. I couldn't live with the knowledge that the best I could possibly do would be to be a well-known novelty act. I want to think it's possible for the stuff I write to have an impact of its own merit.
At the same time, you won't get far without being true to yourself. So you have to find a way to be who you are, openly, without transitioning.
