Body hair keeps us warm, and for some of us is also erotic. Since we no longer need it for its mammalian functions (thanks, cashmere). The tricky thing about it is that for some people it's a turn on, and for others it's repulsive. Some people love to indulge in the scents, moisture and sensations provided by thick hair. Others like to get creative with it and make designs by shaving it or dying it. And some just can't get far enough away from it!
