In this study, we explore the physiological and behavioral correlates of two stone‐directed and seemingly playful actions, the repetitive tapping and rubbing of stones onto the genital and inguinal area, respectively, that may have been co‐opted into self‐directed tool‐assisted masturbation in long‐tailed macaques (i.e., “Sex Toy” hypothesis). We predicted that genital and inguinal stone‐tapping and rubbing would be more closely temp…
