A woman's vulva are the two fleshy mounds between her legs, each side of the opening of her vagina. The vulva is made up of two sets of "lips". The bigger outer ones are called the labia majora and the inner ones are called the "labia minora". They can vary in size from woman to woman and also each side of the vulva may not be the same size. They are sexually sensitive and swell during sexual stimulation and intercourse. At the front of the vulva is your clitoris, and at the back of the vulva is the back passage called your anus.
