Porn ED is caused by too much porn. It is something men can normally reverse by stopping consuming porn for 4-8 weeks. It's not like sitting down and watching one porno will destroy your ability to get an erection without porn and it is not like watching one or two videos will make you physically addicted to porn. It's just like alcoholism. Drinking one or two shots of vodka and/or occasionally getting drunk does not make you an alcoholic. What makes you an alcoholic is continued excessive exposure that you choose to do. It's not like alcohol is this evil thing that will suck you into its trap. You become an alcoholic when you are self medicating your problems. It's the exact same thing for porn related ED.
