I'm beginning to wonder if coming out is necessary at all.
I came home from school last week to find that my mom had come home from work early. She was there to meet me at the door, and I was still wearing my binder. At first I got startled and held my backpack in front of my chest, but she didn't notice. I went in and put my stuff down, and when I gave her a hug, she kind of pushed me away by the shoulders and looked down at my chest questioningly. I panicked and said, "What? What're you looking at?" and she said, "Your shirt." That was it. Since then I've worn my binders around her and my stepmom, and they haven't said a word, though I'm fairly certain they both noticed (I'm rather "well-endowed", and the disappearance of my breasts are noticable to people who know me).
Another thing: I was hanging out in the kitchen with my mom while she cooked. I was talking about my childhood and some friends I used to have. (She wasn't around at that point in my life--we were reunited for the first time in 16 years in '07.) I said, "They always made me play the girl parts. I don't know why," talking about the games I played with my little guy friends. She replied, "Because you were a girl--or they thought you were." This leads me to believe that she knows I don't see myself as a girl.
My mom is transsexual too (or was, she'd probably say), so I know she sees the signs of my ->-bleeped-<-. If I came out to her, she'd probably say, "Ok, that's cool" and the only thing that would change would be my pronouns and maybe my name. I might be "son" and "boy". But at this point, I don't give a ->-bleeped-<- what pronouns or endearments people use with me. No one tries to make me be female. I'm free to act and live as a male who's called "she" and "Katie". So, until I need help getting HRT or surgery, is there even any point in me coming out? I don't think so.
