How to know you'll turn out trans?

Hey there,

I recently found out Kris Tyson is now trans. She had a wife and a child before the transition. This kind of made me wonder. How can anyone be sure they won't turn out trans? Like what made you (to any trans people out there) make the switch?

To add a little context. I am a man, straight maybe a tiny bit bi. I have a some traits/interests that would typically be "reserved" (please excuse my terminology here and there) for women.

For instance, I dance a lot. I have even started ballet dancing. And in the past I had an eating disorder. Now I know this may sound a kind of bigoted or stereotypical. But I don't mean it that way, this is purely based on statistics.

However I feel in no way that I am in the wrong body. I like being a man, I like the idea of masculinity, and I like being a man who dances. (Okay granted, I did not like the eating disorder)

But it makes me "worried" if I do end up trans when I already have a wife and children. I want to know before I get all of that done you know what I mean? Tyson probably wanted too, now that I think about it.

Bottom line: How did most trans people know they were trans?
