Hello there. I can understand your concern. Masturbation excess can be harmful and cause pain, discomfort etc. But doing it upto thrice a week can be good for you. It will help in coping up with nightfalls. You will not get night falls. Your old sperms can be let out to make way for the new ones which are constantly being produced. Also, masturbation is known to tackle stress. Additionally, eat a high protein diet, drink lots of water and eat a lot of greens and vegetables. Best regards. Dr. Anil Kumar Jain
