Engaging in both sexual and affectionate behaviors with a romantic partner is often beneficial for adults’ sexual and relationship satisfaction and promotes relationship stability. However, prior research has primarily examined either adults’ sexual or affectionate behaviors, and has yet to explore patterns of sexual and affectionate behaviors and their associations with sexual and relationship satisfaction. In the current paper, we used a person-centered approach and latent profile analysis to identify specific profiles of adults’ physical behaviors in same-gender and mixed-gender relationships, and examined associations of these profiles with sexual and relationship satisfaction. Adults (N = 336, 85.4% LGBTQ+; 45% women, 30% men, 38.6% gender-diverse; M_age = 29.07 years) who were currently in a committed romantic partner relationship for at least six months completed online surveys. We found that a 3-profile solution best fit the data and identified the following profiles: Infrequent Physical Behaviors, Affection-focused Behaviors, and Comprehensive Physical Behaviors. Adults in the Infrequent Physical Behaviors profile were less sexually and relationally satisfied than adults in the other profiles. Adults in the Comprehensive Physical Behaviors profile were more sexually satisfied than the two other profiles. Further, profiles did not differ for mixed-gender compared to same-gender or gender-diverse couples. Our findings have implications for understanding the diversity in adults’ physical behavior patterns, including how clinicians might better support adults’ sexual and relationship satisfaction.

与浪漫伴侣进行性行为和深情行为通常有利于成年人的性满足和关系满意度，并促进关系稳定。然而，以前的研究主要考察了成年人的性行为或深情行为，尚未探索性和深情行为的模式及其与性和关系满意度的关系。在当前的论文中，我们使用以人为本的方法和潜在概况分析来确定成年人在同性和混合性别关系中身体行为的特定概况，并检查了这些概况与性和关系满意度的关联。成人 （N = 336,85.4% LGBTQ+;45% 女性，30% 男性，38.6% 性别多元化;M_年龄 = 29.07 岁）目前处于忠诚的浪漫伴侣关系中至少六个月，完成了在线调查。我们发现 3 种概况解决方案最适合数据，并确定了以下概况：不频繁的身体行为、以情感为中心的行为和综合身体行为。与其他档案中的成年人相比，不频繁身体行为档案中的成年人在性和关系方面的满意度较低。综合身体行为概况中的成年人比其他两个概况更符合性需求。此外，与同性或性别多元化的夫妇相比，混合性别的概况没有差异。我们的研究结果对理解成年人身体行为模式的多样性具有意义，包括临床医生如何更好地支持成年人的性和关系满意度。
