As someone who's trans, you should know that being outed as autistic can ruin transition, depending on where you live.

I'm autistic and trans- my gender therapist diagnosed me, but NOT on paper, because she said "I don't want to ruin your life. Once you've had surgery, feel free to reach out for an official diagnosis if you want."

MANY places/states will deny you HRT/Surgery if you're diagnosed as autistic, because many doctors believe that autism means you don't have the self awareness to known what you really want.
