I am an 18 year old male. I have gone through some stages of puberty noticeably. However I have 3 problems. At 18, I still have peach fuzz all over my face. There are a few coloured and hardened strands, but not anything really noticeable. Secondly, while I have got lots of pubic hair and underarm hair, my foreskin doesnt retract naturally, and it doesn't stay back at all. Finally, my penis has many little white bumps all over it, and hair seems to grow out of them. Should I be worried?
