Sexorcism

More About Sexorcism

If someone believes spirits have possessed them or their spouse, they may try exorcisms.  For instance, it has been reported that a man in Shanghai had sex with the mother of his girlfriend, claiming that she was possessed by the evil spirit of her late husband. He proposed that this spirit was contributing to the woman's depression and other health issues. This man said that only by having sex with a younger man like himself would she be able to get rid of this demonic influence.

Although some individuals firmly think that exorcisms can expel evil spirits from the body, this isn't the only way the term is used. In a more informal sense, it can also refer to sexual acts that appear so intense that they might, in theory, ward off evil spirits. In the United States, for instance, there was a case where someone accused a neighbor of having a "sexorcism" after hearing loud sexual noises one night and placing a letter on their door.
