Sharing my story as how I became aware as it relates to me.

I suspect I'm autistic, and don't quite understand masculine or feminine gender norms. (I mean, I learned what they are, but they seem nonsensical to me.)

After I learned about the "Gender Apathetic" identify, it seemed to fit my feeling towards my gender, which is to say, I don't care about it. (Although appearing like my birth gender tends to draw less unwanted attention.)

Also, I learned that gender expression and gender identity can be different, which helped solidify my feelings about being non-binary, since I dress mostly like my birth gender, but I do not feel any other significant attachment to it.

I got one of the easy identities and no gender dysphoria or people giving me odd looks. I know a lot of other people have it harder. Knowing about my identity did help me to understand myself.
