Now, to the best of my Master's knowledge, I am female. I never once considered coming out to him, because he would not take it well. He is not awfully bigoted or anything--more of a "live and let live" attitude--but he wouldn't understand and probably wouldn't even make an effort.
I want to just come out to the new Master, but I have no idea how he'd take it--I've never met him before. I don't want to start at his gym female and then have to come out after everyone's used to me, but I also don't want to tell him I'm trans and have him report disggustedly back to my Master.
