I am 34 years old. My problem is low semen secretion. I am unable to build physical relationship with my wife for 2 or 3 times. For 1st time usually I do not face any problem. But in 2nd time or 3rd time in a same day when I want to sex with my wife face issue. Penis erected perfectly but the amount of semen secretion is very less. In 3rd time penis erected but no semen secretion.
