What a porn addiction is? A pornography addiction, is an addiction where someone compulsively engages in sexual activity with the usage of porn. The word compulsively is key here. It means: performing an action persistently and repetitively without it necessarily leading to an actual reward or pleasure. And this touches on the problem. Is porn addiction a classified addiction? Although there seem to be extreme cases of “porn addiction”, Porn addiction itself is medically neither classified as a mental disorder nor an addiction in the DSM-5 or ICD-11. Which both are extremely important classification manuals.
