Opposition to pornography
Reasons for opposition to pornography include religious objections, moral values, feminist concerns, as well as harmful effects, such as pornography addiction and erectile dysfunction. Pornography addiction is not a condition recognized by the DSM-5, the ICD-11, or the DSM-5-TR. The definition of "porn" varies between countries and movements, and many make distinctions between pornography, which they oppose, and erotica, which they consider acceptable.
