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.
