Buy it for yourself or your partner. Male Sexual Function Male sexual function requires a strong sexual desire and adequate penile erections.
Sexual drive is affected by nutrition, stress, fatigue and medications.
The duration, intensity and predictable nature of a man's erection is a function of the inflow being greater than the outflow. Trapping of blood in the penis causes an increase in blood volume, and therefore, size and rigidity. Scientists have recently discovered the exact natural substance necessary to allow the trapping to occur. Cyclic-GMP is the substance. Men can now function longer, better and in a more reliable way.
