Recent years have seen an increasing number of studies on relationship extradyadic behaviors (Pinto and Arantes, 2016; Pazhoohi et al., 2017; Silva et al., 2017; Fisher, 2018). However, much is still to learn about the impact of these extradyadic behaviors on subsequent relationships that an individual may have. Our main goal was to study the association between past extradyadic behaviors - inflicted and suffered - and current relationship quality, sexual desire and attractiveness. Specifically, we aimed to: (i) Understand if past extradyadic behaviors are related to current relationship quality, sexual desire, and self-perceived and partner's attractiveness; (ii) Identify possible gender differences in these variables. For that, 364 participants (251 females and 113 males) were recruited through personal and institutional e-mails, online social networks (e.g., Facebook), and the website of the Evolutionary Psychology Group from the University of Minho. All participants completed a demographic and relationship questionnaire, followed by questions related to extradyadic behaviors and self-perceived attractiveness, the Perceived Relationship Quality Components (PRQC) Inventory, the Sex Drive Scale (SDQ), and the Importance of Partner's Physical Attractiveness Scale (IPPAS). For those currently involved in a relationship, results suggested that extradyadic behaviors (both suffered or inflicted) are linked with current low relationship quality and high sexual desire in the present. In addition, individuals who perceived themselves as being more attractive tended to have a higher sexual desire and higher relationship quality. Overall, men reported higher levels of extradyadic behaviors and sexual desire, gave more importance to physical attractiveness, and perceived their current relationship as having less quality than women. These results add to the literature by focusing on different variables that play an important role in romantic relationships, and have important implications.
近年来，关于关系外性行为的研究越来越多（平托和阿兰特斯，2016年；帕佐希等人，2017年；席尔瓦等人，2017年；费舍尔，2018年）。然而，关于这些关系外性行为对个体后续可能拥有的关系的影响，仍有许多有待了解之处。我们的主要目标是研究过去遭受和实施的关系外性行为与当前的关系质量、性欲和吸引力之间的关联。具体而言，我们旨在：（i）了解过去的关系外性行为是否与当前的关系质量、性欲、自我感知的吸引力以及伴侣的吸引力相关；（ii）确定这些变量中可能存在的性别差异。为此，通过个人和机构电子邮件、在线社交网络（如脸书）以及米尼奥大学进化心理学小组的网站招募了364名参与者（251名女性和113名男性）。所有参与者都完成了一份人口统计学和关系问卷，随后是与关系外性行为、自我感知吸引力、感知关系质量成分（PRQC）量表、性驱力量表（SDQ）以及伴侣身体吸引力重要性量表（IPPAS）相关的问题。对于目前处于恋爱关系中的人，结果表明，关系外性行为（无论是遭受的还是实施的）都与当前较低的关系质量和较高的性欲相关。此外，认为自己更有吸引力的个体往往有更高的性欲和更高的关系质量。总体而言，男性报告的关系外性行为和性欲水平更高，更重视身体吸引力，并且认为他们当前的关系质量不如女性。这些结果通过关注在浪漫关系中起重要作用的不同变量，为文献增添了内容，并具有重要意义。
