Pornography has become a primary source of sexual education. At the same time, mainstream commercial pornography has coalesced around a relatively homogenous script involving violence and female degradation. Yet, little work has been done exploring the associations between pornography and dyadic sexual encounters: What role does pornography play inside real-world sexual encounters between a man and a woman? Cognitive script theory argues media scripts create a readily accessible heuristic model for decision-making. The more a user watches a particular media script, the more embedded those codes of behavior become in their worldview and the more likely they are to use those scripts to act upon real life experiences. We argue pornography creates a sexual script that then guides sexual experiences. To test this, we surveyed 487 college men (ages 18-29 years) in the United States to compare their rate of pornography use with sexual preferences and concerns. Results showed the more pornography a man watches, the more likely he was to use it during sex, request particular pornographic sex acts of his partner, deliberately conjure images of pornography during sex to maintain arousal, and have concerns over his own sexual performance and body image. Further, higher pornography use was negatively associated with enjoying sexually intimate behaviors with a partner. We conclude that pornography provides a powerful heuristic model which is implicated in men's expectations and behaviors during sexual encounters.

Using data collected from 1,880 heterosexual men and women residing in the United States, this study investigated the associations among gender, pornography consumption, and 20 sexual behaviors observed in popular pornography. Acts were grouped according to whether participants reported engaging or being interested in trying specific sexual behaviors as the (a) aggressor (e.g., hairpulling, spanking, or choking), (b) target (e.g., being spanked or choked), or (c) uncommon and/or degrading sexual activity (e.g., male ejaculation in female partner's mouth, anal sex, double penetration, and ass-to-mouth). Using sexual script theory, we hypothesized greater use of pornography would be associated with greater likelihood of both having engaged in and interest in engaging in these sexual behaviors. We further hypothesized gender differences consistent with pornographic sexual scripts that frequently portray men as aggressors and women as targets of aggression. Hierarchical multiple regressions revealed significant main effects for gender and pornography use on the three categories of sexual behavior but no significant interactions. Higher pornography use was associated with greater likelihood of both engaging and being interested in trying all categories of sexual behavior. Men were more likely than women to have engaged in aggressive and degrading/uncommon behaviors, and women were more likely than men to have engaged in target behaviors. However, men were more interested than women in trying all three categories of sexual behavior. Results provide partial support for sexual script theory; while higher pornography use increased interest and prior engagement in pornography-like sexual behavior, the increases in types of sexual behavior (aggressor, target, or uncommon/degrading) were not moderated by gender.

Personal pornography viewing has been associated with lower sexual satisfaction in both experimental and observational research. The language used to hypothesize this relationship typically suggests that it is frequent viewing, rather than infrequent or only occasional viewing, that is responsible for any adverse effects. When the nature of the relationship between a predictor and a criterion depends on the levels of the predictor, a curvilinear relationship is indicated. Nevertheless, studies have assumed linearity in their analytical approach. Curvilinear relationships will go undetected unless they are specifically tested. This article presents results from a survey of approximately 1,500 U.S. adults. Quadratic analyses indicated a curvilinear relationship between personal pornography viewing and sexual satisfaction in the form of a predominately negative, concave downward curve. The nature of the curvilinearity did not differ as a function of participants' gender, relationship status, or religiosity. But the negative acceleration was slightly more pronounced for men than for women, for people not in a relationship than for people in a relationship, and for religious people than for nonreligious people. For all groups, negative simple slopes were present when viewing reached once a month or more. These results are correlational only. However, if an effects perspective were adopted, it would suggest that consuming pornography less than once a month has little or no impact on satisfaction, that reductions in satisfaction tend to initiate once viewing reaches once a month, and that additional increases in the frequency of viewing lead to disproportionately larger decrements in satisfaction.
