To be honest? I ultimately arrived at the fact that I just feel happier when I present femme-ish. Usually still jeans and a t-shirt though--I'm not particularly hyperfeminine, as that's just not who I am.
I've decided that it works better for me, and that's enough for me.
Is it silly to "swap gender"? Absolutely. All notion of gender is silly, in my experience. We're told to perform certain appearances and actions and ideas, to socialize and be around people in a certain way. People treat you wildly differently (trust me, sigh) when they look at you and bin you as a woman versus a man--you wouldn't believe how stark of a difference it was even with old friends the minute they started physically perceiving me as a woman.
All of us are just trying to get through a wildly gendered world in a way that makes us happy--the least we can do is allow people their choice of the role they play in this grand performance, as all of us everywhere are acting.
'Transition' for me was just finally deciding that I got to pick how I socialize, how I act around people, how I dress, and so on. Someone could call me a man, perhaps--I wouldn't particularly be fond of it, and it would probably come across as unusual to others given my appearance, but surely it's a thing that could be said to me.
(It should be, in my opinion--I don't believe in third parties with no stake making forced decisions for you for what can and can't enter your body--but as someone for whom this is lived experience, you can't do this, especially not at a Walgreens and not without getting LFTs and hormone levels done regularly.)
I get a somewhat similar sensation with enough caffeine now, but the experience of testosterone in my experience is a lot more of a head-rush than caffeine is for present me.
It's kind of neat, because at the end of HRT cycles as the levels shift, it lets me experience varying proportions of one versus the other--it honestly surprised me a lot to experience for the first time how much hormones play into what it's like to be in my head day-to-day.
Ooh, and re: the last question, it's possible that that's something that not everyone experiences--I will say though that that's probably the best way I have to describe what I felt, even though I wouldn't say I actively noticed a buzzing sensation before I started HRT (when my doses are late though, it's definitely something I pick up on).
Many transgender women pre-HRT have very low testosterone levels. It's possible there's some causal arrow between being transgender and having autism, but to be frank much of it could come down to reporting bias, i.e. those with autism are more likely to not care as much about societal expectations and consequently are more likely to embrace being transgender publicly.
This could also be exacerbated by the fact that autism in cisgender women is widely believed to be dramatically underdiagnosed due to gendered societal expectations around behavior and diagnostic tests that only check for traditionally 'male' autistic traits/behaviors.
It's also the case that many individuals transition long after e.g. primary brain development ceases, so it's not particularly likely in my estimation that the body is trying to compensate for past development (given the developmental stage of life is complete).
One recurring theme I've heard from people going from majority testosterone to majority estrogen is a feeling like a continuous 'buzzing' sensation in their head had finally stopped; this is something I personally experience, and there's a certain degree of relaxed serenity that comes with it for me. (This said, experiences vary a lot, and many who have had both primary hormones prefer the feeling of testosterone.)
I personally think that it's a beautiful opportunity to get to experience life through both sets of hormones; it's offered a lot of interesting perspective on my personal notions of 'self', and allowed me to develop empathy for different experiences others experience in their bodies.
Saved me hours in undergrad, was what everyone at Stanford used for quickly communicating ideas and typing up :)
