    I believe that organic sex, body against body, skin area against skin area, is becoming no longer possible, simply because if anything is to have any meaning for us it must take place in terms of the values and experiences of the media landscape. What we're getting is a whole new order of sexual fantasies, involving a different order of experiences, like car crashes, like travelling in jet aircraft, the whole overlay of new technologies, architecture, interior design, communications, transport, merchandising. These things are beginning to reach into our lives and change the interior design of our sexual fantasies. We've got to recognize that what one sees through the window of the TV screen is as important as what one sees through a window on the street.
