The purpose of this study was to analyse the relationship between attitudes toward pornography, self-esteem and feelings about sex in a longitudinal sample of Norwegian adolescent boys and girls. The participants in this study were 261 adolescents who were surveyed in three separate questionnaires from 1999 to 2001 (T0, T1 and T2). Boys reported a more positive self-esteem than girls at T0, T1 and T2. At T1, girls reported more positive feelings for sex than boys. At all points of measurement, boys were more supportive of the attitude “Pornography can be very stimulating” than girls were. More girls than boys agreed to that pornography should be forbidden, but the gender difference was most pronounced at T0. There was no statistically significant correlation between self-esteem and the attitude “Pornography should be forbidden” in the reporting. The association between negative feelings about sex and the attitude pornography should be forbidden among girls was r = -.44 at T0, dropping to r = -.32 at T2. At all times of data collection, there was a relationship between agreeing to that pornography can be very stimulating, a positive self-esteem and positive feelings about sex among girls. Among boys at T2, an association between agreeing to that pornography can be very stimulating, and positive feelings about sex was found. Positive attitudes toward pornography seem more dependent upon positive feelings toward oneself and oneʼs sexuality in girls than in boys.
