This study examines use of Internet pornography by adolescents in Taiwan and the relationships between exposure to Internet pornography and the sexual attitudes and behavior of surveyed teens. Results show that about 38% of the sample had some exposure to Internet pornography. Further, this exposure was associated with greater acceptance of sexual permissiveness and the greater likelihood of engaging in sexually permissive behavior. Most important, this exposure showed sustained relationships with sexually permissive attitudes and behavior when it was examined simultaneously with exposure to traditional pornography, general media use, and demographics.
