"The Going Down Guide" is your basic "Everything you wanted to know ..." guide to oral sex, complete with details (and illustrations) on recommended positions (including "Chairman of the Board"), finding your partner's erogenous zones, techniques (licking, sucking, teasing, hot/cold, etc.), safe sex concerns (including a useful guide on using lubricants and dental dams), and how to gauge how you are doing (For example, if you partner changes the TV channel while you are performing oral sex, you're not doing so good.) What I found interesting were the sections where the authors report the results of their surveys of what men most often say women do wrong, and vice versa. The book also gets into (pardon the pun) analingus, as well as semi-public sex, sub/dom play and multiple orgasms. I needed a cigarette by the time I was finished with the book, and I don't even smoke!
Nice effort, in a format that is practical and useful to its intended readers.
