Pubic Hair Facts
There are many theories behind why humans have pubic hair. One thought is that the hair that grows around the genitals and under the arms lock in sexually stimulating scents called pheromones. For some, scents released from these areas are noticeable and can increase sexual desire. For others, pheromones might not be obvious but may be subliminally sensed. Some people believe that pubic hair keeps our genitals warm. Others believe that the purpose of pubic hair is to prevent dirt from entering the vagina.
Pubic hair is also a natural thing to protect against body friction. Rubbing of skin can irritate and hair helps to decrease this problem. It helps to protect your sensitive areas from redness caused by the skin rubbing. This could also provide a protection of possible irritation during intercourse.
