Answer: Masturbation is rarely harmful. Masturbation is considered by most health care professionals to be normal sexual activity. Experiencing sexual pleasure can be good for you. Frequent rigorous masturbation can cause friction. Scratches and cuts can also be problematic. Using a lubricant can help avoid this problem. Perhaps the most harmful aspect of masturbation is the anxiety and guilt often associated with it. I am frequently asked if masturbation can cause ill health, whether it causes baldness, blindness, madness, you name it! Expressing sexuality through masturbation will not make you physically ill. Anxiety about masturbation can make you feel bad, though. Remember, expressing your sexuality through masturbation can be a normal part of being a man (or woman).
