Billed as a guide to human sexuality by psychologist and sexual educator Hiriart, this book provides an over-view of sexual practices from seduction and kissing to masturbation and wet dreams culled from a variety of fields such as anthropology, science, and psychology. But it is not a guide: there is no real instruction, and while much ground is covered within its 10 chapters, there is no index to help locate specific information. While Hiriart clearly intends to avoid passing judgment on many sexual practices, she makes exceptions, as in the case of sadomasochism. Also, the information is focused on avoiding the transmission of sexual diseases instead of on pleasure itself. The book includes chapters on homosexuality and sex with handicapped partners and is accompanied by a bibliography and extensive chapter notes. While the information itself is valuable, the book is a dull read. Recommended for public libraries with human sexuality collections and large bookstores. Tatiana de la Tierra, SUNY at Buffalo Lib.
