Hi I'm 17 years old and have been experiencing this for about a year now; but have only just looked into it because I thought it would just go. To put it straight I have some sort of hard white ring of skin on my penis, I don't experience any pain, itching or anything else. It gets a bit tight when my penis is erect and the foreskin is pulled back and it also accumulates a strange smell. If anyone could help me figure out what I have and a way to get rid of it I'd highly appreciate it, Thanks :D
