I've come out as trans* to a few people that I know- my mom, my little sister, my dude friend from my new school (I moved and didn't say anything…) and maybe a few people I know can guess, but I don't know. My girlfriend, Mary (not from my old school), knows that I bind, and that I'm "butch" and my little sister mentioned a story about my gender when she was around. I think that Mary knows, considering that about a week and a half ago we were walking around her neighborhood, and she said that I might come out as trans* later in life. Instead of coming out to her, like I should have, I laughed it off and said, "Yeah, maybe." while internally I was dying of a heart attack.
So, should I come out to her officially? I've never flat out told her that I'm trans*, but I've laid out little hints, like how I hate my boobs, and she was there when I packed to play a male role in one of our other friends plays. Would I be really stupid to tell her that I'm trans? I feel like Mary would just laugh and say that she already knew, but I want to properly come out to her. Should I? Someone help, please.
