When I first came out to my mom as trans and gay she was concerned that I wouldn't be able to find a man who would want me if I transitioned. I made the mistake of mentioning, in passing, other gay transmen as a possibility, and now she's having trouble getting her head around her former daughter, now son, dating someone who used to be a woman but is now a man, and not not a woman who used to be a man.
Hmmm. When I put it like that, I'm not sure I get it, either.
