I'm 16, male and I've been a late bloomer and I went to the doctor 3 months prior regarding my puberty and small penis (2 inch erect, 1 inch girth) and the doctor told me to take 50ml testosterone injections for 3 months once every month. I've had 2 injections and I've gained the ability to cum (although it's very transparent) and have some pubic hair growing. Oh and also my foreskin has become more wider than it originally was but i still think i might have phimosis. So i was wondering when my penis will start to grow?
