Hi there! I know this is a scary situation. I think most of us here have had to come out in one form or another to someone we loved not knowing how they would handle it.

For me, my sister tells my mom everything. She told her I was queer way back when and the most recent thing was that I am in a polyamorous relationship. That went over really well. Let me say that I did not ask my sister to tell her anything!

If you are going to write an e-mail to you mom, just be honest about how your partner feels about himself and why he is making this change. Not sure if she's ever heard of Chaz Bono but I think if it were me, I'd tell my mom something like, he is just like Chaz. My mom would know who Chaz is lol.
Not sure she would accept it regardless but at least she would know what I was talking about.

You could refer to it as "top surgery" which is like a mastectomy in women with breast cancer. The surgery may be the same but it's for totally different reasons.

Anyway, I'm not an expert by any means. I just think honesty really is the best policy. It makes things a lot less confusing in my opinion. Doesn't mean I'm right but doesn't mean I'm wrong either.

Best of luck to you and yours!
