For the longest time I just thought that since I had a vagina I had to be a girl. Like, I thought that no matter how I felt, I had to be. Then I saw an episode of Degrassi about a transgender guy, and my very fist thought was 'that's me.' For a long time though, I thought that you had to be straight to be a transguy, I thought I had to like girls, so I denied it. I just didn't know that it was okay for me to be gay. I was pretty miserable until 9th grade when I decided that I was going to figure out my sexuality- I'd been confused about it, so I wanted to have a label for myself. When I was looking up stuff on the internet, I learned that being trans has no effect on being gay, and if I was a guy, it didn't matter whether or not I liked other guys.
Funnily enough, now that I know who I am, I've been able to figure out my sexuality much better. I think the influence of growing up like I HAD to be a girl made me think I liked guys, but when I really began to break down some of the influences in me, I realized that was not the case.
