I have been doing volunteer work all my life. Transitioning did not affect my willingness to do volunteer work. I’ve never had an issue with anyone, and if you ask a me a question regarding my transition that is a legitimate request for understanding, I have no problem answering any question to the best of my ability. However any question of a purient interest, I will probably say some rather unpleasant things about your interest.
I volunteer because I enjoy it. Representing doesn’t enter into it, but I am very aware that I am a representative of my minoity group, and I think I have done a good job of clearing up some people’s misunderstandings or incorrect assumptions.
