Viagra is a medicine guys with erection problems may take to get a hard on during sex. In a short time this blue tablet has become extremely popular.
How does it work? When you get excited blood flows into the penis and is trapped there. A guy can have an erection problem if not enough blood is flowing into the penis or if it flows out too quickly. Viagra helps the penis fill with enough blood without it flowing out.
Viagra does not increase your desire for sex. The hard on comes about as it normally does: by being stimulated sexually.
Common side effects are headaches, facial flushing and an upset stomach. Less common are bluish vision, blurred vision or sensitivity to light.
Taking this medicine without prescription is not without risk! It can be deadly if it is combined with nitrates, for instance found in recreational drugs, like ‘poppers’.
Some think Viagra might increase their pleasure or make sex hotter, even if they don’t have erection problems. But that’s not the case: it is not an aphrodisiac.
