how to tell the difference between if it’s really who I am or just a fetish?

so, for some context: I've been questioning my gender for a few months now, and I've decided on being a femboy. I mean, I could be trans, but that's a post for another day.

Like many people, I found myself through... pleasure. I never wanted to be the man in the situation, always the girl. I've always wondered what it was like to have a girls body... but I quickly became addicted to this type of content, and it has ruined me.

I don't get sexually excited whenever im called a girl. I just have this feel good energy in me, I guess. A bloody good gut feeling, I like to call it. I don't get aroused when I think of myself as a girl. It's just that I have a fear it might be a fetish...
