Not thinking about it
I question myself a lot, but I keep coming back to the answer that I gave when I never thought about it.
I could run myself around in circles thinking about what gender I am and how I fit in with trans narratives and how far I'll need to take my transition, but when it comes down to it,
I always presented myself as genderless in online forums.
I avoided giving genders to the characters I could in my writing.
From the start, I told medical professionals that I was nonbinary.
It wasn't until I started thinking deeply and researching and trying to explain myself to others that I began to question it.
Not that that was bad. Questioning my answer gave me more certainty in it. It also made me think about how my answer interacts with the world. Which it will have to do if it is to live anywhere outside of my head.
