Madonna changed her mind about the title being X, when Spike Lee's film Malcolm X began to be promoted.
Approached with an idea for a book on erotic photographs, Madonna expanded on the idea and conceived the book and its content.
Shot in early 1992 in New York City and Miami, the locations ranged from hotels and burlesque theaters, to the streets of Miami.
One was that she conceived the idea of an erotic photography book during the shooting of the film A League of Their Own in the summer of 1991.
The second one is that Judith Regan, vice-president and editor-in-chief of Simon & Schuster, flew to Los Angeles in March 1991 to meet with Madonna and her manager Freddy De Mann, armed with a proposal for a similar collection of photo-erotica.
It was received negatively by both critics and fans of the singer, who felt she had "gone too far." Through the years, however, critical reception towards Sex has become more positive, with academics deeming it a defining phase in Madonna's career.
