The vulva is the exposed female genital organ, which contains many structures, including the vestibular gland, urethral opening, labia majora and labia minora. Since the vulva is exposed and the vagina secretes a lot of secretions, all of which gather in the vulva, it is easy to cause vulvar inflammation, vulvar itching, and even bacterial and viral infections if you do not pay attention to hygiene. So in order to prevent vulvar infections from happening, it is important to keep the vulva clean and dry. Although washing the vulva can be a good way to prevent bacterial invasion, excessive washing can easily destroy the bacterial flora inside the vagina, so it is best to wash it about 2-3 times a week.
