The most popular and widespread religion in the world, based around the belief that Jesus Christ was raised from the dead and is the Son of God. It is one of the three Abrahamic faiths along with Judaism (its predecessor) and Islam (its successor). Like the other Abrahamic faiths, it is a monotheistic religion believing in an almighty creator god.

Christianity has strict rules surrounding sex: Homosexuality, masturbation, and sex outside of marriage are traditionally seen as sins, and Christian priests are usually sworn to vows of celibacy. This makes Christianity a popular topic in pornography, either for the purposes of creating sacrilegious art or to examine the erotic and psychological tension of sexual repression that often results from Christianity's sexual prohibitions.
