Sex is a 1992 coffee table book written by American singer Madonna, with photography by Steven Meisel Studio and Fabien Baron. It was edited by Glenn O'Brien and published by Warner Books, Maverick and Callaway. The book features adult content including softcore pornography and simulations of sexual acts including sadomasochism.
Madonna developed Sex after Judith Regan of Simon & Schuster publishers suggested a book of erotic photographs. She wrote it as a character named "Mistress Dita", inspired by 1930s film actress Dita Parlo. It was influenced by punk rock and fashion figures including Guy Bourdin, Helmut Newton and Robert Mapplethorpe. The photos were shot in early 1992 in New York City and Miami, in locations including hotels, burlesque theaters, and city streets.
