'My partner was just all over her': jealousy, communication and rules in mixed-sex threesomes

Drawing on findings from interviews with 28 men and women, this study explores experiences related to communication and jealousy in mixed-sex threesomes. Findings suggest that those in relationships often experience feelings of exclusion when engaging in threesomes, although open communication is a method by which the negative effects may be mitigated. Some couples agree on particular rules during their threesomes, symbolically demonstrating the specialness of the relationship as well as protecting it from further progression into non-monogamy. Although communication appeared less important for those having threesomes when not in a relationship, it still played a role in determining participants' use of contraception whether the threesome occurred while in a relationship or not. Study findings are contextualised using the concept of monogamism, with it being suggested that threesomes involving romantic couples can serve to help maintain institutional monogamy, rather than trouble it.
