In all of my memories, I've had the same gender, but I didn't know the word "transgender" until I had a computer with the internet, which was probably when I was 9. Before then, I thought about my gender as the things I like, but if anyone knew I liked, or if I acted upon, I would be thrown out into the streets.
As all of you know, thinking this way has some very negative effects, which thankfully we've confronted.
