Research has suggested that exposure to sexual content affects people's thoughts and behavior, though there is disagreement as to the extent of the effect.[2] Gert Martin Hald, a psychologist at the University of Copenhagen, who authored a study which found that watching "sexually explicit media" only accounted for 0.3 to 4 percent of behavior changes, said, "Our data suggest that other factors such as personal dispositions — specifically sensation-seeking — rather than consumption of sexually explicit material may play a more important role in a range of sexual behaviors of adolescents and young adults."
