Young women ( n = 1,000), visiting a family planning clinic in Stockholm, Sweden, answered a questionnaire about their sexual behavior and if they had seen pornography. Four out of five had consumed pornography, and one-third of these believed that pornography had impacted their sexual behavior. As many as 47% had experienced anal intercourse, which was significantly more common among older women (51%) than among teenagers (31%). The majority valued anal intercourse as a negative experience. As the use of a condom was low (40%) when having anal intercourse, the consequences for the spread of sexually transmitted diseases should be considered.
