Madonna has always made waves with her sexually charged fashions and behavior, but she pushed even more buttons than her cone bra and "Like a Virgin" performance with her X-rated coffee-table book, Sex. The controversial book released in 1992 features Madonna in an assortment of soft-core pornographic photos inspired by everything from sadomasochism to analingus. Her erotic leather one-piece outfit was put up for auction at Christie's in 2004.
