I am 40 yr old and since nearly 7 yrs, I was using" Manforce-50" to get additional sexual benifit. But afterwards, I found that it has gradually reduced my natural power to keep a control on discharge alongwith decrease in potency strength and loss of sexual apetite. So I was situationally bound to use it for some days a month, when required to maintain a normal married life. Now, I feel acute problem of impotency, loss of sexual spirit / desire / apetite alongwith uncontrolled quick discharge. What is its solution?
