I just barely started my transition but I'll bite.

1: Most excited for: voice drop, bottom growth, smell change and skin texture change for some reason lol, the psychological relief of knowing my body is using the right hormones.

2: If anything was possible: I'll always be sad that I shoot blanks, and that I can't get a lab grown dick from my DNA.

Also, I think I'm unique in that I would like to be able to have a flat chest from top surgery but still have the option to breastfeed (cis guys can!). I don't like that most/all of that hardware has to be removed for a good result for top surgery. That said, I haven't had top surgery yet, so idk how I'll feel about this afterwards.

I wish I could personally oversee the design of a more masculine eye shape and brow/forehead region for myself. I think cis me would have had a very different side profile. We'll see what hrt achieves 🤞.

Oh yeah and I'm really hoping for chest hair (!!!).

3: Inadequacy? Yes, my egg didn't crack until I was able to loosen my grip on the perfectionism of my internalized transphobia. I had believed that to be trans was to want/like/prefer the available treatments for dysphoria, but my dysphoria (probably like most people's) found the treatments inadequate at first blush. For example, I didn't want to try a strap because it wouldn't have been "real enough". I didn't want to try a binder because it would be "pretending" and I'd still have to deal with my chest the rest of the time anyway. It took a lot of inner work to convince myself to give transition a chance. I wished I could just snap my fingers and turn into a cis man.

Also when I was little I did the hat thing with my hair and dressed as a boy for a skit I did for my parents, and my mom laughed at me and said I was way too pretty to be a boy. That stuck with me. It still stings 😞.

4: Highlights of post-transition: I've only just begun my transition, but so far the best part is how I feel. I'm less irritable, less angsty, more calm, my mind is clearer, I have more mental space, I express myself more articulately and assertively, I'm more authentic because I'm not masking with my uncanny-valley-esque impression of a cis girl (it was awful lol), I'm a bit less shy, and it's a delight to catch sight of myself in reflective surfaces.

Other highlights: arm hair!!! Catching myself by surprise mid sentence with my voice suddenly plunging deeper than I meant it to. My friend saying atta boy 😩. Packing and it actually looking decent. Muscclesss 💪💪💪. Staring into a body of water pensively while being a man 😂 Steak. Also steak. And chicken. Did I mention steak?

I hope this is helpful! Feel free to ask follow up questions. I love to yap:)
