Coprophilia refers to sexual arousal or pleasure from feces. Some people are aroused by defecating on a partner, being defected on, or by the inclusion of feces in solo or partnered sex play.
As with many theories regarding fetishes or paraphilias, some clinicians suggest that coprophilia originates in childhood, and/or associations between physical pleasure of bowel movements and sexual arousal. Anecdotally, people who are aroused by being defecated on link the interaction to an element of dominance and submission, or BDSM play.
Coprophilia has also been noted in older adults living with dementia, and in individuals labeled with developmental/intellectual disabilities. No research exists to distinguish what this behavior may or may not mean for these populations versus what it means for other groups.
Because of the difficulty in recruiting people to participate in research, we have no empirical data about how many people engage in coprophilic behavior.
