The Kama Sutra and Ananga Ranga (Barnes & Noble Digital Library‪)‬

This edition includes a modern introduction and a list of suggested further reading. 
Kama Sutra is a compilation of timeless wisdom from the third century AD about the arts of pleasurable living. It contains detailed advice on topics ranging from attraction, courtship, seduction, marriage, and sexual union.  Written twelve hundred years later, the Ananga Ranga is an updated version, drawing extensively upon the cornucopia of sexual positions that the Kama Sutra first proposed.  Their sexual candor, along with vivid descriptions of sexual positions, make the Kama Sutra and the Ananga Ranga indispensable guides to couples seeking to enhance their sexual relationship.
