Sex in film is the motion picture presentation of sexuality and love scenes, while an erotic film is one that has an erotic quality intended to create sexual feelings. Nudity in film may be sexual or non-sexual. Love scenes, erotic or not, have been presented in films since the silent era of cinematography. Love scenes have been presented in many genres of film; while in other genres, sexuality is rarely depicted. Many actors and actresses have performed nude/partial nude scenes, as well as dress and behave in ways considered sexually provocative by contemporary standards at some point in their careers.
