Hi

Masturbation is a natural process when a person is getting sexually active and 80% of the boys start it to enjoy before the age of 14 and rest try it after the age of 14. It is not harmful if it is done once or twice a month but excess of everything is bad. Watching porn movies and ending up in Maturbation is  harmful phenomenon as it weakens the Muscular Strength of Penis and induces Early Discharge at slight arousal. You can control this mindset by doing Pranayaam, Dhyan and Meditation when you feel an intense urge to masturbate. This is very helpful and it can entirely change your bad habit. You can give strength to your Penis muscles by applying Shri Gopal Oil on shaft of Penis and increase your stamina by taking Ashwagandha Churan 1 Tsf twice daily with milk and One Tablet of Pushpdhanva Ras twice daily alongwith  of Ashwagandharisht 2Tsf after meals.
