We investigated the reasons for pornography consumption using a bottom-up approach (i.e., open-ended questionnaire) and proposed that those reasons would reflect a short-term mating orientation of individuals that watch pornography and a strategy that should help them to attract or maintain potential mates easier (i.e., a fitness increasing strategies) by enhancing their sexual knowledge through pornography watching. In Study 1 (N = 276), relying on an open-ended questionnaire and a content analysis, we identified 78 reasons for why people claim to consume pornography. In Study 2 (N = 322), we grouped those reasons into categories using a series of factor analyses, resulting in four dimensions of reasons for watching pornography: (1) increased sex drive, (2) enhancing sexual performance, (3) social and instrumental reasons, and (4) lack of relational and emotional skills. The content of these factors supported the idea that the reasons for consuming pornography are reflections of a short-term mating orientation and a way to enhance their sexual knowledge and performance. Individuals with higher scores on the dimensions of reasons for pornography consumptions had higher scores on the Dark Triad traits and sociosexuality, mate-value and slow life history strategies (in the case of enhancing sexual performance dimension). In Study 3 (N = 327), we tested to what extent the factorial structure of the reasons for pornography consumption can be confirmed via Confirmatory factor analysis and tested the convergent validity of the reasons to consume pornography.

我们采用自下而上的方法（即开放式问卷）调查了色情内容消费的原因，并提出这些原因反映了观看色情内容的个人的短期交配倾向，以及帮助他们吸引或维持色情内容的策略。通过观看色情内容来增强他们的性知识，从而使潜在的伴侣更容易（即，增加健康的策略）。在研究 1（N = 276）中，依靠开放式问卷和内容分析，我们确定了人们声称消费色情内容的 78 个原因。在研究 2（N = 322）中，我们使用一系列因素分析将这些原因分为几类，得出观看色情内容的四个维度的原因：（1）增加性欲，（2）增强性表现，（3）社交和工具原因，以及（4）缺乏关系和情感技能。这些因素的内容支持这样一种观点，即消费色情内容的原因是短期交配取向的反映，也是提高性知识和性表现的一种方式。在色情消费原因维度上得分较高的个体在黑暗三合会特征和社会性行为、伴侣价值和慢生活史策略（在增强性表现维度的情况下）方面得分较高。在研究3（N = 327）中，我们通过验证性因子分析检验了色情消费原因的因子结构在多大程度上可以得到确认，并检验了消费色情原因的收敛效度。
