Following the recent exhortations of health communication scholars to continue the study of pornography and its potential impact on health-related behaviors, the present study investigated associations between the frequency of pornography use and six indicators of impersonal sex among a national probability sample of US adults. Impersonal sex has been linked to a variety of important public health outcomes, including STD risk and sexual aggression perpetration. In this study, pornography use was positively correlated with the likelihood of engaging in group sex, having sex with a casual partner, having sex without emotional intimacy, experiencing heightened sexual pleasure during non-relational sex, relational infidelity, and perceiving the receipt of sexual pleasure from others as the best thing about sex. No evidence emerged that these associations were spuriously due to high sex drive individuals being both more likely to consume pornography and engage in impersonal sex. But several were conditional on age. Most importantly, countering the conventional wisdom that sexual media are most likely to affect the sexual behavior of young audiences, the strength of the positive association between pornography use and the likelihood of engaging in group sex and casual dyadic sex was larger among older adults and weaker among younger adults.
