Veronica..
what is your goal with the HRT?...
whatever you decide..you need a clear goal in mind or you will be taking a meaningful health risk and be disappointed...
physical results are not satisfactory without testosterone blocking..you may completely lose function of your penis, you may not...you will definitely go sterile and you can't control how fast..
if your goal is specific and related to how your body looks (breasts/fat distribution), they you have to know that what happens happens...you may gain significant weight with marginal breast growth..thats part of the reason why the transitioners here jump on folks that say they want to start HRT to get breasts....it doesnt work that way all the time...you may want subtle changes, and changes may be quite noticable..
if your goal is mental health, or to test the waters and get the feeling of having the right hormones, then i actually say go for it...but if you are worried about your little friend, then that's not the reason or you are tricking yourself...
get your sperm frozen so if you proceed at least you'll have that...
all the best,
Kate
BTW
Silicone breast implants are not dangerous..its not even clear they ever were unless you just inject the silicon...
i'm getting breast augmentation and i'm using silicon ..
