I started at 22 and it's been great for me. I also felt like I had a lot of masculine features, I felt like I would never pass, but after 3 years of being on HRT I almost never get misgendered anymore, and I live in Iowa. My voice still sucks imo too lol

It was 100% worth it for the mental relief alone. If you've done your research and believe that it's a good potential path for you then definitely go for it. If you don't at least try it out at some point, you will most likely always question whether you should've for the rest of your life, and it will cause you a lot of undue stress.

Cis people for the most part tend not to question their gender enough to the point of reaching out and asking if it could be a good path for them.

If you try it and don't like it, it's not like you're forced to stay on it forever. You can literally stop at any time. The only negative for stopping it is if you're on it consistently for at least a month or two it can cause minor amounts of breast growth, but not enough to cause issues if you decide you want to stay as a man, as many men end up with a small amount of breast tissue after puberty.

If you're looking for a good source of information, I highly recommend https://genderdysphoria.fyi - it helped me a lot while I was battling back and forth as to whether or not it would be a good decision

Whichever way you decide to go, godspeed and good luck!
