how did you know that you were a trans guy and not a butch lesbian? did it have to do with not wanting to have breasts, or was it more that you had an inner identity as male?
i admire your courage
I identified as a butch lesbian for many years but something never felt right. I knew that i was a guy but all my lesbian friends did not want to call me 'he" and this was many many years ago. So I think to answer this it was something that I just knew about myself no matter what anyone said.
Hope this helps.
