Don't do any surgery. In severe cases, it will lead to the disappearance of nerve feelings and the loss of sexual pleasure. The correct way is to turn up the foreskin moderately every day. After a period of time, the elasticity of the foreskin will increase, and finally the effect of turning up naturally will be achieved. Of course, it is still wrapped at ordinary times, which has no effect on sexual life. When inserted, the foreskin will turn up naturally and will not feel pain. Some of my students are numb because of related operations, and this kind of pain is even beyond the understanding of ordinary men.
