would you rather be uncomfortable with your whole body (being without T) or would you rather be more comfortable with your body, but uncomfortable with your growing dick?
the way I see it, i'm sure (correct me if i'm wrong) you don't really like your genitals as they are anyway, so wouldn't you rather be a little more uncomfortable with them, or completely miserable?
you cant get one thing and not another, sure I don't wanna go bald, but chances are I may, and that's just something I am willing to live with.
I didn't really feel any discomfort when I grew (which hasn't been too much growth yet) it didn't hurt either.
chances are you will turn out to like the growth, sure.. maybe you wont, but in my experience I am a lot happier with my genitals because I can feel myself being erect now, it makes me feel like more of a man, I feel like I can understand my arousal better.
Have you ever gone onto xtube and seen videos of transguys genitals?
as for your mom, i cant really help you there, ive always been a selfish person, i believe in survival of the fittest, i need to do what I need to do to survive and be happy, i am the only one that knows the right decisions for me. and if my mom were your mom, i would simply tell her "look mom, I love you, but this is something I need to do, you cant stop it or change it, just accept me for who i am, or we will have to go our separate ways, even if I don't want that to happen"
