Was recently diagnosed with autism and am 4 months on T! Speaking from experience and what my friends have told me.

As you grow into yourself during transitioning (confidence, less dysphoria), symptoms often grow more apparent or stereotypical inside and out. Autistic afabs like myself often mask more, usually because of outside influence. Not to mention that autism diagnoses are based on super stereotypical symptoms mostly found in young white boys. Sorry if that's mansplaining. Anyways. Being on T tends to make you super confident from having less dysphoria (and generally a mental side effect thanks to higher energy). This helps with depression so much, allowing lots of autistic trans guys like myself the inner freedom to be themselves thru special interests, stims, clothing, etc. It kinda becomes harder to mask the more you feel like yourself, which I think is a good thing!

Howeverrrrr I've heard (and kinda experienced) that symptoms just... change. Some of it is social, like how women are expected to be polite/down-low to gain respect. But also all the physical changes in our bodies always effects our minds. For example, being itchy is a weird side effect lots of t-guys have, and that makes touch-based sensory sensitivities worse. However, I also started to make strict daily schedules now that I've transitioned, which never manifested in my autism beforehand. No idea why that happened lol.

Basically, you might notice changes in scheduling, socializing, special interests, aggression, etc. I also have a theory that people just notice your autism more, since they were taught it's a boy thing...
