Book excerpt: When Forbes, an anthropology student, stumbled upon a museum dedicated to sex she hesitated to apply for a job. Twelve years later she proudly sports her title as Curator of Sex. Here she invites readers to travel from suburban garages where men and women build sex machines, to factories that make sex toys, to labyrinthine archives of erotica collectors. She asks readers to grapple with the same questions she did: when it comes to sex, what is good, bad, deviant, normal? Do such terms even apply? And, in our hyper-sexualized world, is it still possible to fall in love?
