Some of the previous studies have shown gender differences in the perception of jealousy; men generally demonstrate higher response to sexual infidelity (SI), whereas women to emotional infidelity (EI). Studies on jealousy between homosexual partners showed, that gay men tend to be more sensitive to EI, whereas lesbians expressed more concerns regarding SI. These studies suggest that the type of jealousy might depend on the sex of respondent's partner and on the sexual orientation.

The aim of this study was to explore the experience of jealousy in heterosexuals and homosexuals using an online survey, and to examine whether sexual/emotional jealousy differs depending on a respondent's partner's sex. The study involved 286 participants, 137 men (mean age 27.8, SD = 5.88) and 149 women (mean age 25.07, SD = 5.32), who were in a relationship. All respondents completed a set of anonymous questionnaires about partner's jealousy (PJ) (Anticipated Sexual Jealousy Scale; Scale for Three Types of jealousy). To compare the differences in the type and extent of PJ between heterosexuals and homosexuals we performed one-way ANOVA and Fisher test.

Men in a relationship with a woman (versus men in a relationship with a man) showed higher SI jealousy (p = 0.001), and similarly, women in a relationship with a woman (compared to women in a relationship with a man) also reported higher SI jealousy (p = 0.001). Women in a relationship with a man (versus women in a relationship with a woman) showed higher jealousy to EI (p <0.001). In men we found no difference in the level of experiencing PJ in response to EI. We analysed the dataset also according respondents sexual orientation. A significant difference was found between the experience of SJ in homosexual men and women, women showed higher SJ than men (p= 0.001).

The results differed, depending on whether the analysis focused on sexual orientation of the respondent or the sex of the respondent´s partner. Categorizing heterosexual/homosexual individuals might therefore be problematic. The benefit of this study was in taking into account the partner status, which wasn't considered in previous studies. Similarly to previous studies, the results of this study suggest differences in the experience of PJ in relation to the respondent's partner's sex.
