Hello, because the foreskin can't turn up, it can accumulate a lot of pollution and even stones in the foreskin, causing balanitis and urethritis. It can also induce penile cancer. Treatment is mostly circumcision. If you don't have surgery, you should pay attention to cleaning and get up often to clean. If you can't determine the specific cost of treatment, I suggest you go to the hospital for examination and treatment. I wish you good health!
