Abstract Despite advances in research into minority sexual identities, bisexual identity research has been limited. Studies conducted to date suggest that bisexuality is often perceived as a ‘transitional’ identity and bisexual individuals in relationships are often perceived to be either straight, lesbian, or gay based on the gender of their relationship partner. The current couple-based study focuses on the experiences of bisexual individuals in mixed-sex relationships and how bisexual identity may impact sexual and relationship satisfaction of both members of the couple. Cross-sectional data were analyzed from both members of 142 mixed-sex couples (N = 284). Analyses indicated that feelings of illegitimacy of bisexuality and outness to family were negatively associated with sexual and relationship satisfaction of both partners whereas intimacy was positively associated with sexual satisfaction for both partners. The results highlight the importance of acknowledging bisexual identity even in the context of long-term relationships and addressing issues surrounding bisexual identity in its function for sexual and relationship satisfaction with couples.

双性恋身份对混合性伴侣的性和关系满意度的影响

摘要 尽管对少数民族性身份的研究取得了进展，但双性恋身份的研究一直很有限。迄今为止进行的研究表明，双性恋通常被视为一种“过渡性”身份，而关系中的双性恋个体通常根据其伴侣的性别被认为是异性恋、女同性恋或男同性恋。当前基于夫妻的研究侧重于双性恋个体在混合性关系中的经历以及双性恋身份如何影响夫妻双方的性和关系满意度。对 142 对混合性夫妇（N = 284）的两个成员的横截面数据进行了分析。分析表明，双性恋的不合法感和对家庭的疏远感与双方的性和关系满意度呈负相关，而亲密感与双方的性满意度呈正相关。结果强调了即使在长期关系的背景下承认双性恋身份的重要性，并解决围绕双性恋身份的问题在其对夫妻的性和关系满意度方面的作用。
