A pornographic actor/actress or a porn star is a person who appears in pornographic films. Most actors appear nude in films (usually filmed in explicit sexual genres). Most genres have specialists who achieve most of their recognition in a specific niche market such as lesbian sex, bondage, strap-on sex, anal sex, double penetration, semen swallowing or 'teenage' women.
Some legal jurisdictions consider commercial pornography a form of prostitution, though most commercial sex film performers do not regard themselves as prostitutes for various reasons, but rather as artists. Most notably these performers are not paid directly by their sexual partners for the sex, but both are paid through a studio.
