pornographic

adj. showing or describing sexual acts and intended to cause sexual arousal

Pornography or porn is, in its broadest state, the explicit representation of the human body or sexual activity with the goal of sexual arousal and/or sexual relief. It is similar to erotica, which is the use of sexually-arousing imagery for mainly artistic purposes. Over the past few decades, an immense industry for the production and consumption of pornography has grown, due to emergence of the VCR, the DVD, and the Internet, as well as the emergence of social attitudes more tolerant of sexual portrayals.
