Does pubic hair serve a purpose?

There's no clear reason why we have pubic hair. Some say it was for babies to hold onto, others say it's to trap pheromones to attract the opposite sex, and yet others say it's for cushioning during intercourse to prevent irritations. No matter the original purpose, it is not needed and the only problem you may have is ingrown hairs. If you shave or wax regularly for a while you shouldn't have that problem.
