Look at control, not at a count of videos. If you use more than you meant, hide it, lose sleep, and cannot cut back, treat it as a problem worth changing.
People search “signs of porn addiction” hoping for a test. A useful check is: Did I try to stop and fail. Do I need more extreme material to get the same effect. Is this costing sleep, work, sex with a partner, or self-respect. Do I plan my day around getting alone with a screen.
If several of those are yes, you do not need to wait for a label. Change the environment, track days, and get professional help if mood, relationships, or functioning are going down.
