From puberty to erectile dysfunction, Suzi Godson's 'Sexploration' (Amorata Press) is an encyclopedia of tawdry topics that leaves no gland unturned. You begin with a tour of the nether regions that covers all of your body's titillating parts in about two pages. Yet there's plenty here your junior high gym teacher never mentioned in sex ed, or probably even knew about.

Sure, the basic techniques -- kissing, petting, intercourse positions -- are covered, but there's also plenty that you may have only read about in unnerving spam e-mails: plugging, whipping, spanking and even zoophilia. Never heard of that one? Read up on it and you'll never look at a donkey the same way. In addition to the 'Sexploration' orgy of pert explanations, Godson also offers ratings on the risk factors of various practices and preparation tips. Most chapters also include personal testimonies from readers of Godson's sex column to make the reader comfortable about, well, almost any topic.
