1. Higher Risk For Genital Warts: 
If you shave your pubic hair, you are putting yourself at a higher risk of contracting genital warts. Although pubic hair doesn’t completely prevent it, it helps avoid skin on skin contact with someone who may already have it. Genital warts are warts that are located near or on the genital areas. In a female, that means on or near the vulva (the outside genital area), vagina, cervix, or anus. In a male, that means near or on the penis, scrotum, or anus. Warts appear as bumps or growths. They can be flat or raised, single or many, small or large. They tend to be whitish or flesh colored. They are not always easy to see with the naked eye, and many times a person with genital warts doesn’t know that they’re there.
2. Skin Problems In Your Private Area:
Removing your pubic hair naturally irritates and inflames the hair follicles, leaving microscopic open wounds. Frequent hair removal is necessary to stay smooth, causing regular irritation of the shaved or waxed area. Many doctors say it is not unusual to find patients with boils and abscesses on their genitals from shaving as well as cellulitis, an infection of the scrotum. Being on the private parts, these skin issues are often more uncomfortable than they would be on other parts of the body.
3. Pubic hair actually protects you:
Among protecting you from diseases and skin problems, pubic hair helps you to prevent foreign particles like dust and pathogenic bacteria from entering your body. Dust and bacteria are often times accredited to creating terrible irritation.
4. Pubic Hair Contains Pheromones
Scientists believe that pubic hair retains sexual secretions that we know as being called pheromones. This is what attracts us to each other. The body gives off more pheromones as you sweat and those secretions are retained in the pubic hair regions.
