Predicting high risk sexual behaviour in heterosexual and homosexual men: the roles of impulsivity and sensation seeking

Abstract

Impulsivity and sexual sensation seeking were examined as personality correlates of high risk sexual behaviour - unprotected sex with multiple partners - in samples of heterosexual (n=112) and homosexual (n=104) men.
