Pornography use, demographic and sexual health characteristics among university students: a gender-based comparative study of non-users, non-problematic users, and problematic users

Limited gender-based research has compared sexual health among pornography users (PUs) and non-users, including non-problematic pornography users (non-PPUs) and problematic pornography users (PPUs), particularly in non-Western cultures. A 2022 cross-sectional study involving 450 Iranian university students categorized participants as PUs or non-users based on 12 months of use. PUs were further classified as non-PPUs or PPUs using the 'Problematic Pornography Use Scale' cutoff point, with comparisons of demographic and sexual variables made between these groups. Pornography use was reported among 39.6% of students, including 51.7% of men and 33.6% of women. In general, 9.5% of participants were PPUs, including 17.4% of men and 5.6% of women. PUs were mainly men, had fewer children, shorter marriages, lower religiosity, and lower levels of education. Compared with non-users, PUs reported earlier sexual relationships, lower satisfaction with sex frequency and communication, and greater rates of extramarital relationships, masturbation, sexual desire, and sexual distress. PPUs reported more sexual desire, pornography use, masturbation, and extramarital affairs than non-PPUs. Similar patterns in demographics, sexual history, and health were observed in pornography use across genders. The regression indicated being male (OR: 2.42, 95% CI: 1.44–4.06), having lower education (OR: 0.89, 95% CI: 0.81–0.97), fewer children (OR: 0.64, 95% CI: 0.48–0.86), higher masturbation (OR: 1.31, 95% CI: 1.14–1.49), more extramarital relationship (OR: 1.69, 95% CI: 1.07–2.67), less religiosity (OR: 0.87, 95% CI: 0.82–0.93), more sexual excitement (OR: 0.79, 95% CI:0.62–1), and more sexual distress (OR: 1.20, 95% CI: 1.02–1.32) were associated with pornography use. Two-way ANOVA found no significant effects of gender or pornography use on sexual satisfaction. Women had worse sexual function regardless of usage. Pornography users, regardless of gender, experienced higher sexual distress.
