Pornography (often abbreviated porn) is the portrayal of sexual subject matter for the exclusive purpose of sexual arousal. Pornography may be presented in a variety of media, including books, magazines, postcards, photographs, sculpture, drawing, painting, animation, sound recording, phone calls, writing, film, video, and video games. The term applies to the depiction of the act rather than the act itself, and so does not include live exhibitions like sex shows and striptease. The primary subjects of present-day pornographic depictions are pornographic models, who pose for still photographs, and pornographic actors or “porn stars”, who perform in pornographic films. If dramatic skills are not involved, a performer in pornographic media may also be called a model. (Wikipedia)
