Porn addiction is a real issue for many men.
In the same way that something like video game addition is, and that is only if it prevents you from doing work, going to school, being healthy, etc.
Porn is not 'bad for society'. A world without porn is a world with more sexual violence.
No. It's a physical addiction. It can lead to extreme problems with actual relationships and physical intimacy. If someone spends ten years looking at porn and then has a girlfriend and has sex, it's like going from an IMAX theater to a flip-book. The dopamine levels in your brain have numbed your sensations.
No. Just no. It can happen, but it's clearly not the majority.
It's like saying that someone drinking wine is an alcoholic. That's an oversimplification.
