Are you ready to look like this when you are older?

"Meow"
Seriously though, maybe think about it from a reverse perspective. Are you cis enough to not be trans?
Are you ready to grow out your body hair, and grow a beard? Which is all the rage these days. Most straight women like guys with body hair, it drove me nuts.
Are you ready for your bones to get more masculine. This can't be reversed.
I fought it for years before I knew what it was. I used to be rather androgynous and a painter, I drew girls a lot, and one of my girlfriends pointed out I was drawing myself it made me depressed and I did art less. I used to get called a ->-bleeped-<-, and got miss'd on occasion when I had longer hair, but I didn't like men, I like women, and tried to man up, thinking if I just found the right woman I would feel complete, that this would go away. Then when I was face to face with it, I ran away into another relationship for a few more years. That doesn't work, it never goes away.
At the very least the hormones should be helping you from getting more masculine.
HRT will not make your waist much smaller, depending on your ribs, you are young and could try "waist training" or try gaining weight to get more feminine curves. Someone on ->-bleeped-<- said they did three month cycles of gaining fat and loosing it, eating a lot of ice cream for example.
Wishing you the best. ox
