Satisfying romantic relationships often feature high levels of nurturance and eroticism. Consensually non-monogamous (CNM) individuals may experience these with additional partners, potentially reducing the need for both to be present in a primary relationship to achieve satisfaction. We assessed how nurturance and eroticism relate to relationship satisfaction in single-partnered (n = 289) and multi-partnered (n = 335) individuals. We also compared relationship behavior (single vs multiple current partners) and identity (monogamous, n = 217 vs CNM, n = 399). Compared to multi-partnered individuals' reports of their primary relationship, single-partnered individuals reported similar satisfaction and nurturance, and higher eroticism. Across single- and multi-partnered individuals, nurturance and eroticism were positively associated with relationship satisfaction, with no upper level interactions. Instead, interactions emerged when assessing relationship identity. Among monogamous individuals, nurturance and eroticism also did not interact, meaning the positive association of one was consistent across levels of the other. For CNM-identified individuals, however, nurturance and eroticism interacted; nurturance was more strongly linked to satisfaction when eroticism was low, while eroticism was only linked to satisfaction when nurturance was low. When nurturance was high, there was no association between eroticism and satisfaction. Longer relationship durations were linked to lower eroticism and higher nurturance, regardless of partner number or age. Findings suggest that nurturance and eroticism contribute to satisfaction differently for monogamous and CNM individuals, with CNM individuals fostering highly satisfying relationships even when eroticism is low. This study provides a nuanced understanding of how these factors contribute to satisfaction across diverse relationship forms.

一夫一妻制和双方同意的非一夫一妻制关系中人们的养育、色情和关系满意度。


令人满意的浪漫关系通常以高水平的养育和色情为特色。双方同意的非一夫一妻制 （CNM） 个体可能会与其他伴侣一起经历这些，这可能会减少双方都出现在主要关系中以实现满足感的需要。我们评估了养育和情色与单伴侣 （n = 289） 和多伴侣 （n = 335） 个体的关系满意度的关系。我们还比较了关系行为 （单身与多个当前伴侣） 和身份 （一夫一妻制，n = 217 vs CNM，n = 399）。与多伙伴个体对其主要关系的报告相比，单伙伴个体报告了相似的满意度和养育，以及更高的情欲。在单伙伴和多伙伴个体中，养育和情色与关系满意度呈正相关，没有上层互动。相反，在评估关系身份时出现了互动。在一夫一妻制的个体中，养育和情色也没有相互作用，这意味着一个的积极关联在另一个层面上是一致的。然而，对于 CNM 身份的个体，养育和色情相互作用;当情欲较低时，情色与满意度的相关性更强，而当养育度较低时，情色仅与满意度相关。当养育率高时，情欲和满足感之间没有关联。更长的关系持续时间与较低的色情行为和较高的养育有关，无论伴侣数量或年龄如何。研究结果表明，养育和色情对一夫一妻制和 CNM 个体的满意度的贡献不同，即使较低，CNM 个体也能培养出高度令人满意的关系。 本研究对这些因素如何促进不同关系形式的满意度提供了细致的理解。
