Abstract

There is a lack of research concerning self-identified bisexual men who have sex with men (BMSM), specifically regarding their self-identification as top, versatile, or bottom and their sexual behaviors. As a result, this study seeks to examine the use of top, versatile, and bottom identity labels among a group of self-identified BMSM and to describe their sexual behaviors, examining any possible associations between sexual positions and condomless anal sex. This study recruited 278 BMSM, who ranged in age from 21 to 69 years old (M_age=44.92, SD_age=10.74). This study recruited participants via websites, e-mail, and social media. All participants self-identified as bisexual men who have sex with other men. The majority of sample participants were married to a woman (32.7%) or single (30.7%), held a university degree, and lived in urban areas. Participants indicated relatively high bisexual identity acceptance levels (8.03 on a scale from 1 to 10). The survey included three categories of questions, encompassing sociodemographic information, sex role self-identifications, and (un)protected anal sex behaviors. Regarding typical anal sex behaviors, 41.4% of BMSM self-identified as bottoms, 30.3% as tops, and 28.3% as versatiles. The study found significant differences among BMSM for all types of anal sex practices based on sex role identities. Versatile men more frequently reported condomless receptive anal sex, whereas tops were the most likely to report partaking in condomless insertive anal sex. Finally, self-identified bottom BMSM perceived themselves as having shorter penises and being younger in age than BMSM self-identifying as tops, versatiles, or as older in age. This study shows that sexual position self-labeling among BMSM is complex, as well as the need for further research.

摘要

缺乏关于自我识别的双性恋男人与男人发生性关系（BMSM）的研究，特别是关于他们的自我识别为顶，多才多艺或底律以及他们的性行为。因此，本研究试图检查一组自我识别的BMSM中顶部，多功能和底部身份标签的使用并描述其性行为，并检查性姿势和无避孕套肛交之间的任何可能关联。这项研究招募了278名BMSM，年龄从21岁到69岁不等（M_年龄= 44.92，SD_年龄= 10.74）。这项研究通过网站，电子邮件和社交媒体招募了参与者。所有参与者都将自己标识为与其他男人发生性关系的双性恋男人。大部分样本参与者已与女性（32.7％）或单身女性（30.7％）结婚，拥有大学学位并居住在城市地区。参与者表示相对较高的双性恋认同接受度（8.03，从1到10）。该调查包括三类问题，包括社会人口统计学信息，性别角色自我认同和（未保护的）肛门性行为。在典型的肛交行为中，BMSM的41.4％为底部，30.3％为顶部，28.3％为多才多艺。该研究发现，在BMSM之间，基于性别角色身份的所有类型的肛门性行为均存在显着差异。多才多艺的男性更经常报告无避孕套的接受肛交，而上衣最有可能报告无避孕套的插入性肛交。最后，自我识别的底部BMSM认为自己的阴茎短，并且年龄比BMSM自我识别的顶部，多功能或年龄大一些。这项研究表明BMSM中的性位自我标记很复杂，并且有待进一步研究。
