This does not mean that anything is wrong, it is simply a personal preference. Some people do not enjoy the sensation of prostate milking or any other anal stimulation. Similarly, bacteria from the rectum can travel elsewhere if a person does not wash their hands thoroughly after a prostate massage. If a person massages the prostate with dirty hands, this could introduce bacteria into the area. Prostate massage also presents a small risk of prostate infection. However, a very aggressive technique could, in theory, cause minor injury to the skin or rectum.Īlso, prostate massage, especially when it is intense or forceful, could be painful. Prostate milking is not usually dangerous.
