Hello Thanks for your query,based on the facts that you have posted it appears that you have been indulged in masturbation since many and now facing problems related to sexual activities. 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 getting good erection.and delay ejaculation. 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. If you are planning to be out for couple of days please do not take Tadalfil or Vigra ,These drugs are to be taken only on demand when you are planning to have sex with female partner. If you do not get satisfactory results with these drugs you will need to undergo following tests to find out the cause of your ED, 1) Serum Testosterone levels 2) Duplex Ultrasound scanning of penis to rule out arterial insufficiency or venous leak as a cause of your ED.
