Kamagra helps men who suffer from ED to respond to sexual stimulation. An erection is caused when arteries in the penis relax and widen causing more blood to flow into the penis. This results in an erection. If the nerves associated with this process are not functioning properly then the penis can struggle to become erect. Kamagra increases the blood flow to the penis allowing a man to get and maintain an erection whilst he is sexually aroused.
Since Kamagra enhances and maintains an erection, sexual stimulus and arousal is required for the drug to take effect. Using kamagra (unlike some other generic viagra alternatives) a man can respond to romantic and erotic stimulation during a sexual encounter. Once it is over his erection goes away.
