Mixed-gender threesomes (MGTs) are a type of consensually nonmonogamous sexual encounter involving three people of more than one gender. Little research has been conducted on MGTs, and what little work does exist is limited to college students, who may actually be less experienced with MGTs than older adults. The present study investigated attitudes toward, interest in, experiences with, and outcomes of MGTs in two samples (college N = 231; online N = 1342), comprised of 907 heterosexual and 666 sexual minority participants in total. Results indicated that participants reported neutral-to-positive attitudes toward and moderate-to-high levels of interest in MGTs (81% indicated some degree of interest). MGTs involving familiar others were preferred to those involving strangers. Men, sexual minority individuals, and participants from the online sample reported more favorable attitudes toward and greater interest in MGTs as compared to women, heterosexual individuals, and participants from the student sample. In addition, 30% of participants indicated having experience with a MGT. Sexual minority individuals reported more experience with MGTs and more positive outcomes than did heterosexual individuals. In addition, on average, participants reported that their MGT experiences "met expectations." Overall, these results indicate that MGTs are a common sexual behavior that often results in positive outcomes, especially among sexual minority individuals. Additional research on this understudied topic is needed, particularly as it relates to outcomes and the role of MGTs in consensually nonmonogamous relationships.
混合性别三人组（MGTs）是一种共识性的非一夫一妻制性行为，涉及到三个以上性别的人。关于 MGTs 的研究很少，而且现有的研究工作仅限于大学生，他们实际上可能比成年人更少经历 MGTs。本研究在两个样本（大学生 N=231；在线 N=1342）中调查了对 MGTs 的态度、兴趣、经验和结果，共有 907 名异性恋者和 666 名性少数群体参与者。结果表明，参与者对 MGTs 的态度呈中性到积极，对 MGTs 的兴趣处于中等偏高水平（81%的人表示有一定程度的兴趣）。与陌生人相比，参与者更喜欢与熟人参与 MGTs。与女性、异性恋者和大学生样本参与者相比，男性、性少数群体和在线样本参与者对 MGTs 的态度更积极，对 MGTs 的兴趣更大。此外，30%的参与者表示有过 MGT 经验。性少数群体比异性恋者报告了更多的 MGT 经验和更积极的结果。此外，平均而言，参与者表示他们的 MGT 经历“符合预期”。总的来说，这些结果表明，MGTs 是一种常见的性行为，通常会带来积极的结果，尤其是在性少数群体中。需要对这个研究不足的话题进行更多的研究，特别是关于结果和 MGTs 在共识性非一夫一妻制关系中的作用。
