Throughout history and throughout the world, people have reported sexual contact with various supernatural creatures. Many people believe that “sex demons” were born out of the need to explain topics that are generally considered taboo. Usually, unintended pregnancy, miscarriage and promiscuity can cause anger and persecution.
Jewish folklore tells of Lilu, a demon who visits women while they sleep. His feminine counterpart is Lilin. These demons were a particular source of anxiety for mothers because they were known to kidnap children. Ardat Lili was another succubus who would visit men at night to continue her demonic race. The incubus was Irdu Lili, who would visit human women to ensure they would produce his offspring.
