In spite of a growing presence of pornography in contemporary life, little is known about its potential effects on young people's sexual socialization and sexual satisfaction. In this article, we present a theoretical model of the effects of sexually explicit materials (SEM) mediated by sexual scripting and moderated by the type of SEM used. An on-line survey dataset that included 650 young Croatian men aged 18-25 years was used to explore empirically the model. Descriptive findings pointed to significant differences between mainstream and paraphilic SEM users in frequency of SEM use at the age of 14, current SEM use, frequency of masturbation, sexual boredom, acceptance of sex myths, and sexual compulsiveness. In testing the model, a novel instrument was used, the Sexual Scripts Overlap Scale, designed to measure the influence of SEM on sexual socialization. Structural equation analyses suggested that negative effects of early exposure to SEM on young men's sexual satisfaction, albeit small, could be stronger than positive effects. Both positive and negative effects-the latter being expressed through suppression of intimacy-were observed only among users of paraphilic SEM. No effect of early exposure to SEM was found among the mainstream SEM users. To counterbalance moral panic but also glamorization of pornography, sex education programs should incorporate contents that would increase media literacy and assist young people in critical interpretation of pornographic imagery.

Introduction Recent epidemiological studies reported high prevalence rates of erectile dysfunction (ED) among younger heterosexual men (≤40). It has been suggested that this “epidemic” of ED is related to increased pornography use. However, empirical evidence for such association is currently lacking. Aim This study analyzes associations between pornography use and sexual health disturbances among younger heterosexual men using four large-scale online samples from three European countries. Methods The analyses were carried out using a 2011 cross-sectional online study of Croatian, Norwegian, and Portuguese men (Study 1; N = 2,737) and a 2014 cross-sectional online study of Croatian men (Study 2; N = 1,211). Chi-square test and multivariate logistic regression were used to explore the associations between pornography use and sexual difficulties. Main Outcome Measures In Study 1, erectile difficulties, inability to reach orgasm, and a lack of sexual desire were measured using the Global Study of Sexual Attitudes and Behavior indicators. In Study 2, ED was measured with the abridged International Index of Erectile Function (IIEF-5). Delayed ejaculation and a decrease of sexual desire were assessed with one-item indicators. Results In Study 1, only the relationship between pornography use and ED among Croatian men was statistically significant (χ2[2] = 18.76, P < 0.01). The association was small and inconsistent. Compared with infrequent use of pornography, moderate but not high frequency of pornography use increased the odds of reporting ED (adjusted odds ratio = 0.53, P < 0.01). In Study 2, no significant associations both between either the frequency or the recent dynamics of pornography use and male sexual dysfunctions were observed. Conclusion We found little evidence of the association between pornography use and male sexual health disturbances. Contrary to raising public concerns, pornography does not seem to be a significant risk factor for younger men's desire, erectile, or orgasmic difficulties.

A substantial increase in religious identification has been observed in most European post-communist countries. As religiosity has been associated with sexually transmitted infection (STI) and HIV vulnerability among young people, this article examined the impact of religious upbringing and personal religiosity (religiousness) on sexual risks among University of Zagreb first-year undergraduate students, using data collected in 1998, 2003, and 2008. Female participants who reported strict religious upbringing were less knowledgeable about human sexuality than other women. Religiousness was negatively correlated with basic knowledge of human sexuality, but again only among women. Contrary to expectations, no significant associations were found between religious upbringing or religiousness and condom use. Both measures of religiosity, however, were related to decreased odds of sexual debut among young women. In the case of male participants, the impact of religiosity was marginal. Religious upbringing was associated (negatively) with sexual literacy and sexual debut-but only at the beginning of the observed period. Overall, religiosity does not seem to substantially reduce STI- and HIV-related risk-taking, particularly among men. Since the observed increase in the proportion of sexually active students during the 1998 through 2008 period was not matched by an increase in condom use, reducing STI and HIV vulnerability among Croatian youth remains an essential task.

According to confluence model theorizing, pornography use contributes to sexual violence, but only among men who are predisposed to sexual aggression. Support for this assertion is limited to cross-sectional research, which cannot speak to the temporal ordering of assumed causes and consequences. To address this issue, we employed generalized linear mixed modeling to determine if hostile masculinity, impersonal sexuality, and pornography use, and their interactions, predicted change in the odds of subsequently reported sexual aggression in two independent panel samples of male Croatian adolescents (N1 = 936 with 2,808 observations; N2 = 743 with 2,972 observations). While we observed the link between hostile masculinity and selfreported sexual aggression in both panels, we found no evidence that impersonal sexuality and pornography use increased the odds of subsequently reporting sexual aggression-regardless of participants' predisposed risk. This study's findings are difficult to reconcile with the view that pornography use plays a causal role in male sexual violence.
