It is commonly assumed that exposure to pornography harms relationships because pornography changes the way that individuals think, feel, and behave in problematic ways. In the current research, we contribute to a small but growing body of work that challenges this assumption by carefully scrutinizing the relational context of pornography use. In contrast to dominant theoretical explanations in this field, we argue that at least some of the apparent negative “impacts” of pornography use on relationship quality may reflect partner dissimilarity in pornography use behavior rather than the consequences of exposure to such materials. Moreover, we further examine a particular type of pornography use—shared use with a partner—which previous evidence suggests may be positively associated with relationship quality. To this end, we sought to test whether dyadic patterns of pornography use, and related attributes, were associated with sexual and relationship satisfaction in two cross-sectional (N1 = 200; N3 = 207) and two longitudinal (N2 = 77; N4 = 277) samples of heterosexual couples. Across these samples, we found consistent evidence that partners who watch pornography together report higher relationship and sexual satisfaction than partners who do not, and notably, this association was not moderated by gender. Independent of this association, we also found evidence of a similarity-dissimilarity effect, such that the solitary pornography use of one partner was negatively associated with their own relationship and sexual satisfaction, but only in cases where their romantic partners used little or no pornography alone. Further consideration of several correlates of pornography use established comparable patterns of results for dissimilarity in attitudes towards pornography, erotophobia-erotophilia, sexual preferences, and sex drive. Importantly, only dissimilarity in sex drive statistically accounted for dissimilarity in solitary pornography use, suggesting that differences in sex drive may be implicated in the associations between pornography use and relationship quality. These findings demonstrate that links between pornography use and relationship health are partially a function of different dyadic patterns of pornography use within couples and do not always suggest relational harm.

但是你的合作伙伴在做什么？关系质量和色情使用之间的关联取决于夫妻内部使用的上下文模式

人们普遍认为，接触色情内容会损害人际关系，因为色情内容会以有问题的方式改变个人的思考、感受和行为方式。在目前的研究中，我们通过仔细审查色情使用的关系背景，为一小部分但不断增长的工作做出了贡献，这些工作挑战了这一假设。与该领域的主要理论解释相反，我们认为至少有一些色情使用对关系质量的明显负面“影响”可能反映了伴侣在色情使用行为上的不同，而不是暴露于此类材料的后果。此外，我们进一步研究了一种特定类型的色情使用 - 与合作伙伴共享使用 - 先前的证据表明这可能与关系质量呈正相关。为此，我们试图在两个横断面（N1 = 200; N3 = 207）和两个纵向（N2 = 77; N4 = 277）样本中测试色情使用的二元模式和相关属性是否与性和关系满意度相关异性伴侣。在这些样本中，我们发现一致的证据表明，一起观看色情内容的伴侣比不观看色情内容的伴侣报告的关系和性满意度更高，并且值得注意的是，这种关联不受性别影响。独立于这种关联，我们还发现了相似-不同效应的证据，例如，一个伴侣单独使用色情内容与他们自己的关系和性满意度呈负相关，但仅在他们的浪漫伴侣单独使用很少或不使用色情内容的情况下. 进一步考虑色情使用的几个相关性，确定了对色情、色情恐惧症、性偏好和性欲的态度差异的可比结果模式。重要的是，只有性欲的不同才在统计上解释了单独色情使用的不同，这表明性欲的差异可能与色情使用和关系质量之间的关联有关。这些研究结果表明，色情使用和关系健康之间的联系部分是夫妻之间不同的色情使用二元模式的函数，并不总是表明关系伤害。只有性欲的不同在统计上解释了单独色情使用的不同，这表明性欲的差异可能与色情使用和关系质量之间的关联有关。这些研究结果表明，色情使用和关系健康之间的联系部分是夫妻之间不同的色情使用二元模式的函数，并不总是表明关系伤害。只有性欲的不同在统计上解释了单独色情使用的不同，这表明性欲的差异可能与色情使用和关系质量之间的关联有关。这些研究结果表明，色情使用和关系健康之间的联系部分是夫妻之间不同的色情使用二元模式的函数，并不总是表明关系伤害。
