When I was about ten (over twenty years ago), I remember briefly thinking that I'd make a really attractive boy. (I'm a straight, cisgender woman). I don't think I'd heard of transpeople (only drag queens) and certainly didn't mention it to anyone.
I'm just thinking that if I was ten and that thought crossed my mind today, would it be different? Would my train of thought be "I'd make an attractive boy. I must be a boy born in the wrong body"? Would I feel like I should tell an adult? Would the adult then tell me I must be trans?
