Mysophilia
Sexual paraphilia from filth
From Wikipedia, the free encyclopedia
Mysophilia is a paraphilia where erotic pleasure is derived from filth.[1] Mysophiles may find dirt, soiled underwear, feces, unwashed people, or vomit to be sexually arousing.[2] Automysophillia is when a person derives sexual pleasure from being dirty or unwashed themselves.[3]

Paraphilias such as coprophilia, urophilia, and emetophilia are all considered subtypes of mysophillia.[3][4] Richard von Krafft-Ebing attributed these types of paraphilias to latent masochism.[3][4]
In culture
The protagonist of the novel Wetlands, and the film based on the book, would be considered a mysophiliac, deriving pleasure from not washing and from dirty locations, such as toilets.[citation needed]
In a famous myth, Napoleon Bonaparte, while campaigning in 1796, wrote to his wife Joséphine: "Please don't wash, will arrive in three days".[5] This can be interpreted as mysophiliac behaviour if it is assumed this was to ensure her clothes, as well as her person, were soiled.[citation needed]
Arthur Munby, 19th-century English writer, and his wife Hannah Cullwick, a maidservant, both wrote extensively in diaries about the dirt accumulated in household tasks. During courtship, Munby frequently requested Cullwick visited him still dirty from her work sweeping chimneys and cleaning boots.[6]
