Bathwater
Bathwater is a niche fetish in which a person's used bathwater becomes an object of erotic interest or intimacy.
Bathwater refers to a niche fetish or kink built around erotic interest in the water a person has bathed in. For some, the appeal is the intimacy of bathing together or sharing a tub; for others, it is the idea of possessing something closely connected to another person's body. It sits within the broader world of consensual kink and object-focused desire. Like any kink, it is practiced privately between consenting adults and is not tied to any particular sexual orientation. The term is uncommon and mostly circulates informally online rather than in clinical or advocacy literature.
