The purpose of this study was to examine jealousy toward infidelity in bisexual individuals. Each participant completed an online survey including a forced-choice question regarding what distresses them more: the emotional aspects of the infidelity or the sexual aspects of the infidelity. Results supported the hypothesis: a higher percentage of bisexual men dating women reported being bothered by the sexual infidelity than bisexual men dating men, bisexual women dating women, and bisexual women dating men. Additionally, there was a gender by relationship orientation interaction where the traditional sex difference emerged when comparing women dating men and men dating women, but the sex difference disappeared when comparing women dating women and men dating men.
