"The Kama Sutra is an ancient Indian Hindu text widely considered to be the standard work on human sexual behavior. A portion of the work consists of practical advice on sexual intercourse. "Kama" means sensual or sexual pleasure, and "sutra" literally means a thread or line that holds things together, and more metaphorically refers to an aphorism (or line, rule, formula), or a collection of such aphorisms in the form of a manual.
