Hello, Inability to cut down on a behaviour is an important marker of addiction related behaviour. Hence your inability to cut down on pornography can be seen as a addictive behaviour. However one symptom cannot be enough to understand your situation and condition. Such behaviour may also be seen in background of other mental health issues like depression, OCD, adjustment disorder, maladjusted temperament, etc. Hence my suggestion for you is to please seek a consultation with a psychiatrist near you for comprehensive assessment and further management. A detailed assessment will be of great benefit to you. Hope this helps you. Best wishes for your health and future.
