Severe and impulsive promiscuity, along with a compulsive urge to engage in illicit sex with attached individuals is a common symptom of borderline personality disorder, histrionic personality disorder and antisocial personality disorder but most promiscuous individuals do not have these disorders. The study measured one-night stands, attitudes to casual sex, and number of sexual partners.
