Hi Tatiana 🙋♀️ Yes you are correct, it does effect everyone differently.
For me I felt the softness of my skin first, followed by a tenseness in the chest skin and muscles. It felt tighter. That was the first month, interspersed with emotional changes.
Calm, worried, brave, scared, sure, to not so sure, all were more prevalent.
As I became more used to the new feelings, things smoothed out, only to have emotional spikes after a dosage increase. After the first month, my breasts started to itch and swell. It would come and go, different times of the day my areolae would swell up and then reduce after a few hours. Itchy, scratchy, achy, tender, sore, throbbing, full and I'm sure there are more words that describe what your boobs will feel like at some point. After 10+ months I've gained an 1 1/2" on each breast. I measure straight down from my collarbone, over my nipple to the crease below to measure them. They may be uneven, that happens at first sometimes, but they tend to equal out eventually. Right now, lefty Lucy just took the lead back from righty Rhonda.
Other things change too, your pee smell changes and body odor may change as well.
Hair will lessen in some areas, while increasing in others. Your pubic air will grow in a more feminine way. Fat may redistribute in your butt, hip, thighs and face.
If you are entertaining the idea of using your genetics for children, get the little swimmers frozen, or there is a chance that ability may be lost. Your sex drive may or may not decrease, it depends on how your medications keep your T levels at just the right spot for you, but erections, if you choose to employ it, will take a bit of coercion.
Remember YMMV....your mileage may vary!
Hugs and smiles, Jessica
One thing hrt doesn't do much for is, facial hair and your voice. Everyone has to work on that.
