Sexual behavior has impacts on health, some of them are sexually transmitted diseases, such as HIV, the increasing rate of abortion among adolescents, and early-age pregnancies. The objective of this study was to determine the relationship between age, sex, exposure to pornography, knowledge, and attitude towards risky sexual behavior. This research was conducted to students at a private university in Banten. The samples of this study were 80 students selected by using simple random sampling method. The hypothesis testing was performed using the formula for testing the difference between two proportions. The research instrument was a questionnaire. The univariate and bivariate analysis was conducted by using chi-Square test. The research findings revealed that the majority of respondents engaged in risky sexual behavior (51.25%). There was a correlation between the variable of sex (pv= 0.001), exposure to pornography (pv = 0.000), and attitude (pv = 0.026) with risky sexual behavior. Respondents who were exposed to pornography had a 31-fold higher risk of engaging in risky sexual behavior compared to those who were not exposed to pornography. Additionally, respondents with a negative attitude had a 2-fold higher risk of engaging in risky sexual behavior compared to respondents with a positive attitude. On the other hand, the variable of age (pv = 0.949) and knowledge (pv = 0.814) were found to have no correlation with risky sexual behavior. Based on the aforementioned explanation, one approach to controlling risky sexual behavior was by promoting the development of a positive self-concept among adolescents.
