Hi, Thanks for writing in. Too much masturbation will not cause cancer but can cause other physical and mental problems. Excessive masturbation around 5 to 6 times a day can get addictive and cause you loss of concentration in doing your regular activities and prevent you from doing your job and study. The appropriate masturbation frequency is 2 to 3 times a week and not more than once in a day. Frequent masturbation also causes depletion of sperm and erectile dysfunction as it affects the mental health. You can do other activities like listening to music, talking to friends and reading a book when you get masturbation thoughts. This will help you to control masturbation. There is no need to stop masturbation completely as it is a normal behavior when done within limits. Please do not worry.
