Several studies using different methods have found that pornography consumption is associated with lower sexual satisfaction. The language used by media-effects scholars in discussions of this association implies an expectation that lowered satisfaction is primarily due to frequent-but not infrequent-consumption. Actual analyses, however, have assumed linearity. Linear analyses presuppose that for each increase in the frequency of pornography consumption there is a correspondingly equivalent decrease in sexual satisfaction. The present brief report explored the possibility that the association is curvilinear. Survey data from two studies of heterosexual adults, one conducted in England and the other in Germany, were employed. Results were parallel in each country and were not moderated by gender. Quadratic analysis indicated a curvilinear relationship, in the form of a predominantly negative, concave downward curve. Simple slope analyses suggested that when the frequency of consumption reaches once a month, sexual satisfaction begins to decrease, and that the magnitude of the decrease becomes larger with each increase in the frequency of consumption. The observational nature of the data employed precludes any causal inferences. However, if an effects perspective was adopted, these results would suggest that low rates of pornography consumption have no impact on sexual satisfaction and that adverse effects initiate only after consumption reaches a certain frequency.
多项采用不同方法的研究发现，色情制品消费与较低的性满意度相关。媒体效果学者在讨论这种关联时使用的语言暗示了这样一种期望，即满意度降低主要是由于频繁但非频繁的消费所致。然而，实际分析假设了线性关系。线性分析假定，色情制品消费频率的每次增加都会相应地导致性满意度的同等降低。本简要报告探讨了这种关联可能是曲线关系的可能性。使用了来自两项异性恋成年人研究的调查数据，一项在英国进行，另一项在德国进行。结果在每个国家都是平行的，不受性别影响。二次分析表明存在曲线关系，表现为主要为负的、凹向下的曲线。简单斜率分析表明，当消费频率达到每月一次时，性满意度开始下降，并且随着消费频率的增加，下降幅度变得更大。所使用的数据的观察性质排除了任何因果推断。然而，如果采用效果视角，这些结果表明，低水平的色情制品消费对性满意度没有影响，只有在消费达到一定频率后，才会产生不利影响。
