Costectomy

[Tracie Lynn]

Surgical removal of all or part of a rib. A procedure popularized in parts of Italy and France during the late twelfth century. Common amongst [crusaders] who spent years separated from their mistresses. [The surgical] removal of the rib was believed to facilitate chastity by allowing crusaders better [mouth to penis] auto-access and the ability to perform fellatio on themselves. Still practiced in parts of rural France.
The procedure is performed only rarely in women.
