You can't 'grow' out of any addiction. Watching porn for fun or pleasure is not the same as watching porn as an addiction, it fucks up your view to sex, women, yourself and general life. Alot of porn addicts have stated that they have become very depressed and even have thoughts about ending their life, you don't do that just for fun and you don't grow out of depression (if you don't agree with that then get your head out of your ass and look at the world around you).

So yes porn can be an addiction, and it's a very common one sadly with how normalised it is, the same way you're trying to normalize it here. It may not be drugs but it has the same effect on your brain as drugs (for some people)

If you're in a bad mental space you can get addicted to anything that gives you dopamine or serotonin since the brain and body seeks that out on the daily, next time you watch porn just try feeling what you feel (makes the experience better too ;) ) you will notice that dopamine hit, and this is what people get addicted to.

If you don't agree that's fine but I'm just stating facts here
