People vary in their choices
Some people masturbate, some do not, and frequency varies. It is not necessary for health, and choosing not to masturbate is also normal. It should be a private, consensual behaviour that does not involve another person without their consent.
Common myths
Claims that masturbation automatically causes infertility, blindness or permanent weakness are not supported by good medical evidence. Concerns should be evaluated based on actual symptoms rather than frightening online rumours.
Comfort and hygiene
Avoid actions or objects that may cause injury, and stop if there is pain or bleeding. Clean any reusable items according to product directions. Seek medical advice for injury, persistent pain or distress.
