Ok, i'm a guy who just turned 18 and still haven't hit puberty. It looked like I started to like 4 or 5 years ago, for example I have some armpit hair and some pubic hair, but then it just stopped, no deep voice, no facial hair whatsoever, no penal growth, hardly any leg hair, no ejaculation, etc. I'm really getting worried about it. Should I see a doctor, or try to suck it up and wait it out.
