Pubic hair actually serves several purposes:
- It's primary purpose is to trap pheremones. This emits an odour which sexually attracts and increases arousal in potential mates.
- It signals that a person has entered sexual maturityand is a valid partner.
- In men it can trap air and therefore help regulate the temperature of the testicles, which is obviously important for men.
- They're a healthy source of protein. Or at least I hope that they are. There was one in my sandwich today.
