Book excerpt: The wryly amusing and revealing story of one man's journey into the swinger lifestyle that pulls back the curtain on this fascinating, and often misunderstood, subculture. An estimated fifteen million strong worldwide, swingers are everywhere - a huge community, hiding in plain sight, whose erotic pastime remains a complete mystery to the rest of us. In Swingland, Daniel Stern outs himself and the secretive society he loves, recounting his ten - year transformation from a lonely guy who couldn't get a date into a veteran sexual adventurer. Swingland is much more than just a titillating exposé - there is also plenty of invaluable advice for those thinking of taking the plunge themselves (be honest, sensitive and hygienic!). Lovingly written, with a keen sensibility, Stern's narrative is as improbably safe as it is fun - and impossible to put down.
