I have developred a white ring
I need advice. Recently ( around five months) I have developed a white ring around the tip of my foreskin of my penis. I am not circumsised. I am 46 years old and never had this problem before. It appears to be slowly increasing too. I have no pain or irritation but when I pull the foreskin back or get an erection or have sex this portion pains as it possibly is tearing. What is this and what should I do?
