Wax is a substance with a variety of uses.
It is used as a way to remove body hair, for example to make it easier to put on latex clothing, by transvestites to look more feminine and by women who want to wear very scanty clothing without showing any pubic hair.
Molten wax from a burning candle is used in BDSM as a way of inflicting painful sensations (wax play).
Filling the ears with wax is an effective alternative to earplugs.
Most wax is obtained from petrochemicals, but beeswax is available (if expensive).
