Pornography consumption is consistently associated with lower marital quality. Scholars have theorized that embeddedness within a religious community may exacerbate the negative association between pornography use and marital quality because of greater social or psychic costs to porn viewing. As a test and extension of this theory, I examine how being married to a religiously devout spouse potentially moderates the link between respondents' reported pornography consumption and their marital satisfaction. Data are taken from the 2006 Portraits of American Life Study. In the main effects, porn consumption is negatively related to marital satisfaction, while spousal religiosity is positively related to marital satisfaction. Interaction effects reveal, however, that spousal religiosity intensifies the negative effect of porn viewing on marital satisfaction. These effects are robust whether marital satisfaction is operationalized as a scale or with individual measures and whether spousal religiosity is measured with respondents' evaluations their spouses' religiosity or spouses' self‐reported religiosity measures. The effects are also similar for both husbands and wives. I argue that for married Americans, having a religiously committed spouse increases the social and psychic costs of porn consumption such that marital satisfaction decreases more drastically as a result.
