 The sex scenes were choreographed by feminist writer and sex educator Susie Bright . The Wachowskis were fans of Bright and sent her a copy of the script with a letter asking her to be an extra in the film . When she read the script she loved it , particularly as it was about women enjoying having sex and not apologizing for it . Disappointed that they never described exactly what was happening in the sex scenes , she asked if she could be a sex consultant for the film and they agreed . The main sex scene set in Corky 's apartment was filmed in one long shot . The Wachowskis believed that this would look more realistic than several shots edited together . Although it should have been a closed set , there were actually many people present , moving the walls of the set in order to allow full movement of the camera around the actors .
