Sex in film is the presence in a film of a presentation of sexuality. Since the development of the medium, the presence in films of any form of sexuality has been controversial. Some films containing sex scenes have been criticized by religious groups or have been banned or the subject of censorship by governments, or both. In countries with a film rating system, films containing sex scenes typically receive a restricted classification. Nudity in film may be regarded as sexual or as non-sexual.
An erotic film is usually a film that has an erotic quality that causes the creation of sexual feelings, as well as a philosophical contemplation concerning the aesthetics of sexual desire, sensuality and romantic love.
Love scenes, erotic or not, have been present in films since the silent era of cinematography. A pornographic film, on the other hand, is a sex film which does not usually claim any artistic merit. Sex scenes have been presented in many genres of film, although there are some in which it is rare. 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.
