Your foreskin is too long, which has affected your normal sex life. You must be circumcised. The buddy in our dormitory only went to Rende Hospital in Yuzhou last week to have a foreskin facelift. When I came back, I said it didn't hurt. The operation was quick. Now I attend classes normally every day, and I haven't seen him rest. I suggest you go to Yuzhou Rende Hospital for an operation.
