Circumcision generally does not affect erection and you can usually have a normal erection after surgery. There is no effect on the erectile function of the penis after circumcision, but proper control of penile erection is needed after circumcision, so as not to cause wound edema, oozing, pain, etc., and even the possibility of suture breakage, incision splitting, etc., which may affect the healing. Therefore, some methods can be used to reduce erection after circumcision, especially for teenagers and young adult patients, to minimize the acceptance of sexual stimulation. Generally after circumcision, sexual intercourse is forbidden in the early stage, so as not to cause the wound to split. After surgery should pay attention to rest, avoid strenuous activities, pay attention to local hygiene, avoid infection, regular review, generally one month to a month and a half or so can recover.
