Mysophilia
Mysophilia is a paraphilia or fetish in which a person experiences sexual arousal from dirt, filth, or unclean conditions. This can mean arousal from dirty objects (clothing, underwear, shoes, unwashed items), play involving filthy environments (mud or trash), or incorporating bodily fluids or other substances that are considered "unclean." Fetish/kink communities sometimes use this term, but more often people just say “dirt fetish,” “filth play,” “dirty fetish,” or lump it under wet and messy play (WAM) or scat play if bodily waste is involved.
Origins of the Term
The word comes from the Greek "mysos," which means “dirt” or “uncleanness,” and "philia," which means “love” or “attraction.” The term was coined by clinicians in the early to mid 20th century, when sexologist were cataloging atypical sexual interests. Today, “mysophilia” is more often seen in fetish glossaries or academic writing than in day-to-day kink scenes.
Why People Are Into It
People are into mysophilia for many different reasons (it's personal!), but here are a few common ones:
Taboo and Transgression
Filth and dirt are strongly stigmatized in most cultures - you aren't supposed to like them. For some people, breaking the rules can be erotic.
Humiliation or Degradation
Being “dirty” or “made filthy” can tie into submission, embarrassment, or loss of status.
Sensory Play
The tactile qualities of mud, grime, or messy substances may be arousing for some.
Safety and Consent
Mysophilia can involve serious hygiene and infection risks (bacteria, parasites, toxic substances). If explored, it should be done in safer, controlled ways (e.g., with non-toxic substitutes like chocolate, clay, or safe WAM products).
