The most comprehensive of modern sex manuals is "The Joy of Sex" by Alex Comfort. A subtitle on the book is "A Gourmet Guide to Love Making." Thirty two colour prints are included and more than a hundred black and white illustrations. In The Washington Post Anthony Storr rather pompously remarked that ". . . the illustrations, of which there are many are frankly beautiful and entirely lack that kind of surreptitious, suggestive titillation that characterises pornography."
