Pubic hair growth is triggered by hormone release, controlled by the Pituitary gland in the brain.
Age is one way, skin disorders can also cause problems.
peeling skin in the pubic hair area is probly not good. i would sugjest you go see a doctor.
In the 1700s, mercury was used to try and cure some STDs. A side effect was losing one's pubic hair. So the STD itself didn't make you lose it, but the treatment did.
Then your f**ked cause that sh*t pretty much means you have crabs.
