Viagra is a medication used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, which helps men get and maintain an erection when they are sexually aroused.

Viagra works by inhibiting the chemical phosphodiesterase-5 (PDE5), which can interfere with the normal process of blood flow in the penis. When PDE5 is inhibited, the blood vessels in the penis relax and widen, allowing for increased blood flow. This increased blood flow can help produce and maintain an erection.

Viagra is taken as a pill and is usually taken about 30 minutes to an hour before sexual activity. The effects of Viagra can last for up to four hours, although the level of potency can vary depending on the individual. Will have to book back to back

It’s important to note that Viagra is not an aphrodisiac and does not cause sexual arousal on its own. It can only help to improve the ability to get and maintain an erection when a man is sexually stimulated.
