Circumcision does not affect erectile function, and it is possible to have a normal erection after the operation. However, for two weeks after the operation, you need to try to control the frequency of erection so as not to affect the incision. Since circumcision only removes the excessively long foreskin, it does not affect penile erection. If some men experience temporary inability to have an erection after surgery, it may be mainly related to local pain and psychological factors. Erections may occur after circumcision, and if frequent erections occur in the early postoperative period, this may lead to increased blood seepage from the incision and pain, or even incision splitting. Therefore, reduce sexual stimulation and try to avoid frequent penile erection within two weeks after the operation. In normal life, pay attention to rest and don’t do too much exercise. At the same time, eat a light diet, do not eat too much spicy and stimulating food.
