Based on your posts I feel like you're so confused. I'm really confused at times, but I'm transitioning because I have no interest in being a boy. I never have, it never made me happy or comfortable. Becoming a girl makes me happy and comfortable. If I was a boy I wouldn't look under my shirt and see my growing chest and be really happy. The bigger my chest gets the more excited I get lol, I've always had boob envy but I didn't realize I was envying the girls, I thought I could just tell a cute pair from a not cute pair lol.
Like suggested already, I suggest making a list. Can you imagine yourself being a man 10 years from now? Can you imagine yourself being a woman? I thought about stuff like that forever, still do in fact. Like I would think about clothes I would wear in different situations. In an office, in a club, in a grocery store, hanging out around the house, school....looking and feeling like a girl was actually something I desired. Looking and feeling like a boy wasn't. That's when I realized I've always felt trapped in male clothes, and that if I had to wear suits, and dress shoes and slacks forever I would NEVER want to get dressed up. But I like getting dressed up. And it wasn't JUST about clothes for me. I started thinking about relationships I wanted to have. I've identified as gay for about 6 years, not anymore obviously, but when I did, all I knew was that I liked men. And I wanted to be with them. The more I thought about it, I realized woah I don't want to be with a man as another man, not that I don't like same sex couples I actually think its so hot when guys make out lol. But I realized I really longed to be someones girlfriend, wife. Looking into my future considering how things would go if I got married as a man or woman and getting married as a woman was how I felt. Pretty dress, bouquet, the word bride even feels better. Something that helps me feel better, is when I get really sad I find myself saying/thinking "Ugh I hate being trans. Why can't I just be a girl? I just want to be a real girl" I feel like I'm sure I'm a girl mentally, because of how badly I want to be/feel like I am one
I could go on forever but I don't want to hi-jack your thread anymore, if you wanna chat shoot me a PM and we can talk more in detail and maybe you can work out your confusion. Good luck bb. And hey, if you are just a cis girl who likes to go by Alex/he sometimes or all the time, that's okay too. As long as you always stay the nice person you are. Don't let confusion get you down. If you are THAT confused just dress how you want and go by the name/pro nouns you want. Do whatever makes you happy.
