amazon's sex stash Hidden deep within the stacks at Amazon.com is a wonderful selection of smut. Start at Amazon's home page. Click on the Books tab. Click on Nonfiction in the Browse menu. Click on Social Sciences in the menu that follows. See it? Between the Popular Culture and Reference sections? It's a list of Amazon customers' favorite porn. Actually, most of the books are about porn. To find the explicit stuff, you have to visit lists such as Health, Body & Mind / Sex and Literature & Fiction / Genre / Erotica. Here's a peek at what Amazon customers have been reading in bed:

List	No. 1 (overall rank)	Another Great Read	Snappy comment
Pornography	(1812)	Making of an X-Rated Video	The last title on this list is Amazon's 1,273,123rd overall. That's a bestseller? Apparently we need more books about porn.
Sex / General	(14)	How to Give Her Absolute Pleasure	Two of the top titles — The Multi-Orgasmic Man and I'm Not in the Mood: What Every Woman Should Know About Improving Her Libido — cancel each other.
Sex / Psychology	(3762)	The Fine Art of Erotic Talk	It's a mystery how kooky stuff such as The Centerfold Syndrome (which argues that looking at pin-ups leads to dysfunction) outsells Masters & Johnson. No wonder we're screwed up.
Sex / Religion	(337)	What the Bible Really Says About Homosexuality	Just thinking about religion and sex in the same room is a huge turn-on. Naughty Adam! Naughty Eve!
Sex / Alternative	(6357)	Deviant Desires: Incredibly Strange Sex	Most of these bestsellers cater to the bondage crowd, although two are about bestiality (Dearest Pet and The Horseman). Also, The Bottoming Book edged out The Topping Book. Someone's gonna pay for that.
Erotica	(1923)	Best American Erotica 2007	No pictures. Damn.
Sex / Manuals	(2369)	Tickle Your Fancy and 101 Nights of Great Sex	If you're looking for quality sex books, start here.
Sex / Instruction	(122)	Good Vibrations Guide: The G-Spot	Further down the list you'll find Raising Sexually Pure Kids, which instructs parents on how to keep kids from touching themselves. Shouldn't that be on the anti-sex bestseller list?

GROUP SEX For its Purchase Circles feature, Amazon.com compiles anonymous bestseller lists of books bought by customers who live in certain cities, work at certain companies or attend or teach at certain universities. Most of the selections are predictable: people who work at Microsoft buy computer books; people who work at banks buy financial books. But there, lurking at No. 8 on the list of 10 books popular with employees of National Semiconductor, is a sign of hope: Laura Corn's 101 Nights of Great Sex.
