An ancient Hindu text, the Kama Sutra dates back to between 400 BC to 200 AD, and is regarded by many as an authoritative encyclopedia of human sexual behavior, and in specific, a canonical inventory of descriptively named positions and accompanying steps for sexual intercourse and other methods of sensual pleasures for the benefit of both partners. An accompanying adult coloring book to the Kama Sutra might be a valuable study aid, a sort of lab manual if you will, by which sexual inhibitions and or anxieties of one or either partner are lessened by expressive drawing and playfulness.
