There are many claims being made about the wonder drug called Viagra. Men all over the world swear by it to help them enjoy a more fulfilling sex life and treat male impotence. However, some of the claims are either exaggerated or simply not true. The drug works by increasing blood flow to the penis. Some men take Viagra to increase their sexual stamina. Although the drug will not actually do so, it will help you to achieve a longer and harder erection. Therefore, you may be able to enjoy a much longer session of sexual intercourse than if you engaged in sex and did not take the drug. The best way to test this is to obtain a prescription for Viagra and try it out yourself.
