Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Masturbation is natural and normal habit. Masturbation is not unhealthy. Even animals masturbate. Masturbation cannot harm your health if done in moderation like once per day. But anxiety and apprehension associated with masturbation habit and misconceptions can harm your health. Stop worrying and concentrate on your career and education.
