I used to did lot of masturbation around 6 years ago. At thar time I was not aware of masturbation is not good for health I used to did masturbation once or twice regularly for around 3 years. When i know that it is not good for my health i immediately stopped but it was late. Now i am living good lifestyle and health food and even i have taken sex supplements (ayurvedic ) for more than 6 months but i am not seeing even 1% improvement in my masturbation time. I am not married. I am 24 years. I do masturbation once or twice in a month. I dont know why medicine is not shiwing any result
