Sex instruction

Sex manuals are books which explain how to perform sexual practices; they also commonly feature advice on birth control, and sometimes on safe sex and sexual relationships.

In the Graeco-Roman era, a sex manual was written by Philaenis of Samos, possibly a hetaira (courtesan) of the Hellenistic period (3rd–1st century BC). Preserved by a series of fragmentary papyruses which attest its popularity, it served as a source of inspiration for Ovid's Ars Amatoria, written around 3 BC, which is partially a sex manual, and partially a burlesque on the art of love.

The Kama Sutra of Vatsyayana, believed to have been written in the 1st to 6th centuries, has a notorious reputation as a sex manual, although only a small part of its text is devoted to sex. It was compiled by the Indian sage Vatsyayana sometime between the second and fourth centuries CE. His work was based on earlier Kamashastras or Rules of Love going back to at least the seventh century BCE, and is a compendium of the social norms and love-customs of patriarchal Northern India around the time he lived. Vatsyayana's Kama Sutra is valuable today for his psychological insights into the interactions and scenarios of love, and for his structured approach to the many diverse situations he describes. He defines different types of men and women, matching what he terms "equal" unions, and gives detailed descriptions of many love-postures.

The Kama Sutra was written for the wealthy male city-dweller. It is not, and was never intended to be, a lover's guide for the masses, nor is it a "Tantric love-manual". About three hundred years after the Kama Sutra became popular, some of the love-making positions described in it were reinterpreted in a Tantric way. Since Tantra is an all-encompassing sensual science, love-making positions are relevant to spiritual practice.
