The 1970s produced quite a mob of sex or love guides. However, Xaviera Hollander's Supersex is unique and simply the best ever written. All of the other guides are concerned--either overtly or covertly--with rules and limits. By contrast, hers includes marvelous how-to sections on such taboo subjects as heterosexual anal sex, light bondage and sex in public or semi-public places. Further, the illustrations are excellent.
