Mons pubis
The mons pubis, also known as the pubic mound, is an area of fatty tissue that sits over the pubic bone. It can be smaller, or more prominent, largely depending on your genetics. Pubic hair usually starts growing on the mons pubis from puberty (typically beginning between 8 and 13 years old). The main role of this part of the vulva is to provide protection and cushioning during sexual intercourse.
Pubic hair
There can be a lot of variation in the colour, density, coarseness and curliness of pubic hair between individuals. Pubic hair reduces friction, provides protection to the urethra and vagina and helps maintain a balanced pH environment.
