[/INST] Hello, I have gone through your query and understand your concern. All these are myth. Some cultures and religions oppose masturbation or even label it as sinful. This can lead to guilt or shame about the behavior. In fact Masturbation is as healthy and normal habit. Masturbation has good effects on your body and mind. Masturbation to be a natural and harmless expression of sexuality for both men and women. It does not cause any physical injury or harm to the body, and can be performed in moderation throughout a persons' lifetime as a part of normal sexual behavior. The risk of having prostate cancer is also greatly reduced. Apart from the medical benefits, masturbation has emotional and psychological benefits. It is a good mood elevator and an excellent stress buster. It also helps improve sexual relationship with yourself as well as your partner. Hope this helps. Please write back for further queries.
