Ever since sex was first discovered, people have experimented with different positions.
Ancient texts like the Karma Sutra contain exotic pictures of different sexual positions.
These books were created to help couples to enhance their relationship,
but also to try to prevent some of the sexual tedium that can settle into a relationship
when people have been together for a long time.
