Gay pornography is the representation of male bodies, and sometimes sexual activity among males, with the primary goal of sexual arousal in a homosexual or bisexual male audience. There is also a tradition, and continuing considerable output, of lesbian pornography; however, the term gay pornography is rarely intended to encompass this.
Although pornography has usually represented the heterosexual orientation of the dominant culture, homosexual explicit material has a long history, reaching back to the Greek Antiquity, if not to prehistory. Practically every medium has been used to represent all-male sexual acts; nowadays, however, the gay porn industry is mostly concentrated in the making of home videos and DVDs, as well as images (still and moving) for viewing on the Internet. Today, gay porn constitutes a disproportionately large part of the pornography industry.
