Needles, sharpened bones, or other tools used in play piercing are removed from the body when the episode is complete, allowing the wounds to heal.
Those who engage in play piercing may do so for self-expression, imitating tribal rituals [citation needed], spiritual self-discovery, sexual pleasure, or entertainment.
Play piercing as part of a BDSM scene can produce an endorphin high, which can last for hours and can induce orgasm in many of the people who experience it.
Improper technique can result in the transmission of bloodborne diseases (due to needlestick injuries, for example) or puncture wounds, but if done correctly there is far less danger of injury or infection than from being scratched by a cat due to the depth of insertion being controlled and the use of a sterilized needle.
Needles may be arranged in aesthetically pleasing configurations such as a smiley face, may be laced together like a corset, or may be used to sew on temporary decorations such as bells using sterile thread.
