Hi... I'm facing the nightfall problem 2 times a week, which cause physical and mental weakness to me... i always feel tiredness... Also, i can't get erection to my pennis because of which I'm not able to do sex... But with the help of viagra I'm able to get blood flow to my pennis veins and I'm able to do sex... These problems are cause beacuse of excess of masturbating in my childhood... I also took treatment from 2-3 doctors, but no one was able to solve my problem.. I'm completely mentally down... even i feel life my problem can't be corrected... If someone says that i can make u fit, then i will be very thankful to him or her... plzz help me out
