Going the other way (f -> m) :
Your clit may well be the first thing that changes. Mine started to grow noticeably after just a few weeks on even a low dose of T.
You will get so fucking horny. Not even for anybody (or maybe that's because I'm ace), just abstractly, distractingly horny. Every day. No, really, every day. Invest in a vibrator. (In my experience this cools off after the first year or so.)
Your facial hair will grow in stupid and scraggly. You'll have weird bald spots. You may grow a neck beard. You probably won't want to shave it. You don't have to shave it. Look weird, who gives a fuck.
It's fine to dress like a frat boy or a mall goth or a lumberjack or all three at once. You can wear cargo shorts and flip-flops. You can go outside looking like you crawled through your laundry hamper to get there. It will feel illegal the first 100 times you do it and then you will be free.
You'll build muscle even if you maintain the exact same level of activity as when you were estrogen-dominant. Muscles are hungry and you will want to eat more. Eat more. Aim for proteins and leafy greens. Watch your cholesterol and salt intake because your blood pressure will probably go up.
Your hemoglobin will also go up. This is nice because anemia sucks, but it can become problematic if it gets too high. Consider donating blood a couple times a year if you can.
Your periods can stop after a couple months, but they might not (mine did). If you stop taking T, they'll come back. If your dosage is too high, they can also come back (excess testosterone gets converted into estrogen - this also happens to naturally testosterone-dominant people).
Voice changes start around the couple-month mark and your voice will be weird for a while. The initial drop is chaotic and squeaky, then it will settle, but it's probably not done changing. Keep using and stretching your voice, because I'm seven years in and while my voice has mostly found its range I've lost a couple semitones off the top and added them to the bottom in the last few years. Also, cis people are terrible at clocking T-voices, so don't worry about it. Plenty of cis men sound just like you. Seriously.
Crying might get harder, or it might just get weirder. I attribute most of my lack of tears to being happier these days, but strange things make me misty-eyed. Hard to disentangle what's psychology and what's endocrinology.
You'll get real hairy and its fine. Yes on your belly. Yes on your chest. Yes on your back and your knuckles and around your nipples. You'll have shoulder hairs long enough to braid. You'll get hair in places you didn't know hair grew and you'll have bald spots in places you never thought about being bald. Unless you're a competitive swimmer or cyclist, don't fuckin worry about it. Get weirded out by how smooth Hollywood men are instead. Why are we waxing these men like sports cars?
Love the fuzz. Love the armpit stank and the weird-smelling pee and the sweaty back (you'll run hotter after a while). Love the voice cracks, they'll be gone soon. Love your flattening butt and your thinning lips and the new parts of your forehead you get to see as your hairline changes. Love your body, by God, love your body! You made it! It's yours!
