Porneia is sexual behavior that is thought to be 'wrong', 'bad', or immoral. Of course what might be moral in one society could be considered immoral in another. e.g. Is it wrong to have sex before marriage? Is it wrong to have sex with someone of the same sex? What porneia is and what it is not depends on the religious or personal beliefs of the majority.
Porneia is not allowed and is against the rules of the Jehovah's Witness religion. Even flirting is not allowed.
Porneia involves 'immoral use of the genitals, whether in a natural or in a perverted way'. This includes oral sex, anal sex, and manipulation of the genitals between individuals who are not married to each other. Porneia does not require skin contact, copulation, or sexual climax.
