Seeing this a bit late, but it's...been a journey in discovery, I suppose
I knew I liked dresses and dolls as a really young puppy, but that wasn't all that weird; both of my parents were hippies, and I -also- liked action figures, transformers and "boy stuff" so it was fine for them, then that all kinda got pushed down
Fast forward and I recall being like "I mean I wouldn't mind having x, but I'm fine being a guy too" and "I like cross dressing because it's hot but I also just really like it, I guess? It's not that much of a kink it just feels nice."
I got the usual school bullying of misgendering but it felt weird whether they called me a boy or girl. That came to make sense when it finally clicked that I'm non binary; it took time pressure, ADHD medication and still some introspection to realise that though
It wasn't until I started to see myself really aging into a man that l realised "oh no I need to do something about this right fluffing now"
So it took a lot of shocks to my system because I was oblivious to myself, and it's less that I always knew and more that I (eventually) discovered that I always was :3
