First off, whatever you choose to do with your pubic hair is entirely your call and don't let anyone ever tell you otherwise.

Although waxing and shaving have become popular in recent years, it turns out there's a rather important benefit of pubic hair. It turns out that it can act as a protective barrier against bacteria while also acting as a "cushion" that can help avoid injury to the skin. This cushion also comes in handy during any type of physical activity that puts pressure on your lady bits. In an interview with Glamour, obstetrician/gynaecologist and women's health professional Sherry Ross, M.D explained how public hair can prove beneficial.

"Suspected theories, some medical and some not, include that pubic hair prevents dirt and other floating germs from entering the vagina, it keeps our genitals warm, and it’s the perfect cushion during sex, bicycling, and other forms of exercise that put pressure on your vagina".

Dr Ross recommends that good hygiene practices are essential if you're going to keep your pubic hair au naturel. This basically means washing the area with soap and water, particularly after exercise and during your period. This isn't the first time we've heard of how pubic hair can prove advantageous either. Recent research collated by The University of California determined that those who preferred frequent grooming were more likely to contract a sexually transmitted disease. The results indicate that eight percent of non-groomers versus 14 percent of groomers reported a history of an STI. Commenting on these results, Jennifer Gunther M.D. said:

"Anecdotally, I see many cases of skin irritation among women who remove pubic hair, but I’m the first to admit that’s not the highest quality evidence. Ingrown hairs and infections are known consequences of hair removal and some can be very severe, and these kinds of infections can sometimes land women in the emergency room or even the operating room for drainage of an abscess".
