While it is not recognized in the DSM-5, the concept of toucherism is closely related to frotteurism. Both behaviors involve touching strangers without their consent, generally in public places. But whereas frotteurism involves rubbing one’s pelvic area against another person, toucherism occurs when someone uses their hands to touch erotic parts on a stranger’s body (e.g., buttocks, breasts, or genitals) without permission. A subtype of toucherism, called hyphephilia, associates sexual pleasure with touching or rubbing someone’s skin, hair, fabric, leather, or fur.
