Hi, Circumcision is one of the simplest surgeries done by very general surgeon and several graduate medical practitioners (MBBS). It hardly takes 20-30 minutes and you can go home immediately. You would need dressing of the surgery area every day. SInce the head of the penis is sensitive to touch, you might feel mild discomfort for the first few days, as there is no skin covering to protect the sensitive area.
Usually there wont be any complications. Certainly not any for your sexual future. In fact your sexual life and sexual health are likely to be better after circumcision.
