Well after coming out (mom, I'm a guy in a girl body) the people I came out to still call me "she" even when nobody else is around. I figured it would be obvious, but I guess it isn't.
I don't know about asking them to though, I don't look male and they probably don't see me as male and it would probably just make everyone uncomfortable (including myself.)
Sigh, still, my situation is better than most and for that I am thankful. Just the petty things.
