I did, I came out as "gay" when I was 17, but it felt incredibly... wrong. I thought that I would be able to forget about the whole transgender thing and just be fine with a male partner, but I realised that the way I feel about my gender is completely separate from my sexuality. I had no doubts in my mind when I would go online as a 10-15 year old kid and call myself a STRAIGHT FEMALE... it felt right, I didn't feel like I was lying to anybody.
After about a year and a half of coming out as "gay" I couldn't take it any more, I was getting constant headaches, my heart was racing all the time, I would never get any sleep, I'd just stay up all night quietly crying. I was just incredibly unhappy, I had to tell my mother the truth, and I'm extremely glad I did, I have an appointment with the endocrinologist next week.
