Ablutolagnia is a fetish for bathing, showering, and other forms of washing. This word comes from the Latin word abluto, meaning washing, and lagnia, a Latin root which comes from the Greek word for lust, lagneia.
One of the first known uses of the term came from J.E. Schmidt’s sexually focused dictionary “Lecher’s Lexicon,” released in 1967.
Ablutolagnia is sometimes called ablutophilia.
