Sexual Identity Confusion. Non-Binary? Trans? What even is gender among us autistics?

Preface: Forgive me if I screw up terms, I never really grew up with them.

Am I correct that in autism it's common for us to not have any specifically strong identities tied to our biological sex?

With the exception of childhood, over time it felt like everyone became either "male" or "female" and I was left still as... just me. I can barely understand it, how some people can feel strongly male or female. Aren't we just... us? DNA and bone, a brain? And yet I see so many people strongly embrace some nebulous concept of gender and it's always left me a bit lost.

Is this common with autism? Am I different? If it is common with autism, are most of us Non-Binary then? What would we be?
