"People aged 18 to 34 are most at risk of pornography addiction (or compulsive sexual behavior disorder related to pornography viewing). In this age group, 5.4 percent of people are at risk," said Anna Ševčíková, a researcher at the Institute for Psychological Research at Masaryk University, at the conference. The majority of Czechs, including both men and women, find it acceptable to watch pornography in long-term relationships.
