Let me clear little more on ED in men.
Erection issues develop when the male organ is deprived of enough blood at the time of lovemaking. Premature ejaculation starts when men are anxious about the intimate session
For erection trouble, sildenafil citrate acts on the correcting the blood flowing to the male sexual organ and thus making it possible for them to have harder erection. Another chemical dapoxetine works on the brain and delay the ejaculation process in men. This makes it possible for men to hold off ejaculation.
These two issues are quite common in men. Any man with active sex life can suffer from these conditions. Fortunately though there are drugs and therapies available with the help of which you can help.
