The purpose of this study was to explore the relationship between pornography use and sexual behavior in young adults from two culturally different countries. Data were collected in an online survey among German (n = 1,303; G) and Polish (n = 1,135; P) university students aged 18 to 26 years. Pornography use was associated with engaging in a greater variety of sexual activities (e.g., sexual role playing, using sex toys; G > P) rather than with a high number of sex partners or condom use consistency. The differences between the samples were found primarily for females (in anal sex experience and age at the first sexual intercourse; G > P).
