I keep mixing up transexual and transgender in my mind, and I know it. It's kinda driving me nuts now, because with all the talk about it I've got them mixed up again.
I had a fairly similar childhood, crying to sleep because I wanted to be a boy, and screaming at my mother whenever she tried to get me to wear a dress. One time it was so bad I cried and screamed as my mom dressed me and tried to get me in the car for picture day. I was so distressed that they had me change back into jeans and a shirt. Though I do feel that's more of a societal thing. I was just fine as a child if they let me be a tomboy, and I was disappointed when I didn't develop like other girls. I was also heavily maternal, wanting a child of my own since I was five.
However, a strange thing happened when I started becoming more sexual: I wanted a penis. I kept getting this weird feeling like something was missing. Even now when I'm with other girls (and sometimes even with guys) I feel like I should be able to thrust into them and feel something. I never could fantasize from a female perspective, only from a male perspective. Nothing's been able to replace the sensation that I keep craving. It's been the most frustrating experience in my life, to the point that when I feel that way I can get anxiety attacks, and even become so frustrated I wind up crying. Nothing can sexually satisfy me, because it feels like there are nerves that aren't being stimulated, even though there's nothing there. It literally feels like I should be able to reach down and grab that particular organ.
Personally, even if I hate my body for those sensations, I love my life as a wife and mother. And that, thus far, takes priority over being sexually satisfied. My husband is just fine with me going out and working while he stays home and takes care of the kids. With short hair and no make-up, I look really boyish. I've taken on plenty of roles that guys normally take, and been accepted in them. I guess it's also kinda nice being in a place where that's possible.
I've often wondered about what would happen if one of these types had a gender change before or around puberty, especially men. MtF trans seem to have it the hardest, since the testosterone has permanently changed their vocal cords, and they will always have a masculine structure. Kim doesn't have to worry about all of that. She can now live without stress (as far as those things go) as a girl without having electrolysis, voice lessons, acting lessons... To be able to recognize something this early and do something about it would take away a lot of stress, and allow a more natural transition to the "chosen" sex.
