Shaping Sexual Behaviors & Sexual Scripts

A central question in the study of pornography consumption is whether consumption influences risky sexual behavior. In this research, we focus on one key aspect of risky sexual behavior, the accumulation of sexual partners. Using longitudinal latent class analysis of a nationally representative sample, we determine distinct trajectories of pornography consumption. We then use hurdle models to relate membership in these trajectories to the initiation of sexual activity and accumulation of sexual partners. Even with controls for likely confounds (such as risk-taking propensity and relationship formation), we find that adolescents with a trajectory of early and regular pornography use are more likely to report the initiation of sexual activity and nearly double the number of sexual partners as those with a low-use trajectory. This research is of sociological interest because pornography consumption is becoming increasingly common well before adulthood, suggesting that recent cohorts of emerging adults may be more likely to engage in risky sexual behavior through the accumulation of multiple sexual partners.
