Emotional and sexual jealousy as a function of sex and sexual orientation in a Brazilian sample.

The goal of the present study was to compare the relative distress of homosexual and heterosexual Brazilian men and women on scenarios in which they imagined their partners sexually or emotionally involved with another person, using a forced-choice paradigm and continuous measures. Participants were 68 heterosexual men, 72 heterosexual women, 42 homosexual men, and 35 homosexual women. On the forced-choice questions heterosexual men (39 on one question and 37 on the other) were more upset than their female counterparts (21 on one question and 15 on the other) by scenarios of sexual infidelity than those of emotional infidelity. On questions using continuous measures no significant difference was found between pleasurable sex and attachment scenarios for heterosexual women or heterosexual men. On the highly upsetting scenarios heterosexual men discriminated between flirting and both pleasurable sex and attachment scenarios, being less disturbed by the former. In contrast, heterosexual women were equally distressed by the three scenarios. Scores for the homosexual men and homosexual women fell in between those of the heterosexual men and heterosexual women and did not show a clear cut preference for the sexual infidelity or the emotional alternative on the forced-choice paradigm. However, on the continuous measures of jealousy homosexuals resembled heterosexuals of the opposite sex. There was no evidence that jealousy would be less intense among homosexuals although reproductive outcomes were not at risk.
