Hello Thanks for query. You had been indulged in masturbation since many years and now facing problems related to sexual activities and general weakness.. First of all there is myth in a mind of common man that excessive masturbation is the reason of all sexual problems But I would like to state that it has been discussed in scientific forums all over the world and proved scientifically that masturbation does not have any negative effect on any organ or system in the body.All the problems that you are facing now are mind related and due to anxiety. Following measure will help you to boost up your confidence and improve your health and sexual potency. 1) Practice regular exercise for 45 minutes followed by meditation for 1/2 an hour in the morning. 2) Take high protein diet rich in vegetables and fruits and Vitamin A,C,D,E.and Zinc 3)Take anti oxidants like Almonds 5-6 everyday.. 4) Avoid alcohol and smoking.. Though it is harmless, excessive and frequent habitual masturbation does affect quality of erection and delays ejaculation.Please try to reduce the frequency of masturbation by keeping yourself busy in activities like sports,reading ,social work etc so that you will not get free time to masturbate. There are no medicines that can increase size of the penis. Dr.Patil.
