In this excellent article by Ari Tuckerman in Psychology Today, he argues strongly that pornography isn’t addictive.
Sex might be difficult to resist and may be hard to control, but it is not a mystical external force that makes people cheat on partners, get addicted to sleeping with hundreds of people or see you hopelessly addicted to pornography.
For porn to be addictive there must be at some level a belief that sexuality is corrupting and harmful. That acting on certain desires can take you on a slippery slope to deviant behavior or behavior that will interfere with your life goals.
All these presumptions leave out agency and a person’s ability to self-direct. They presume that people fall prey (ah-la-Adam to Eve in the garden of Eden) to lust and that they will perform acts from which they never recover.
Pornography isn’t like alcohol. It doesn’t have any more control over your actions than you allow it.
