What is "Viagra"?
Viagra is a medication mainly used to treat erectile dysfunction in men, but it is not an aphrodisiac and does not increase sexual desire. It works by increasing blood flow to the penis, which helps men achieve and maintain an erection suitable for sexual activity. Viagra typically needs to be taken orally about 30 minutes to an hour before sexual activity.
