There are literally scientists who went into these studies genuinely believing in porn addiction who were eager to study it and its effects who came out no longer believing in it. Why? Because they're good scientists who changed their minds in the face of new evidence.
The key point in studies like this is that they always expect porn-related problems to go up as porn use goes up, and you would expect that because that's how every addiction works from gambling to cigarettes to alcohol to crack cocaine, but what they actually find is that the people with the most distress over their porn use is actually related to how religious they are, not how much porn they're watching. This is significant, because it means people who identify as "porn addicts" are not actually watching more porn than the average person; They just feel worse about it because they think they shouldn't be watching it AT ALL.
I really can't stress this point enough; Are there people whose lives are badly impacted by watching 22 hours of porn a day? Sure, they do exist and they have my sympathy, but the majority of cases of "porn addiction" are completely religiously motivated and have nothing to do with how much porn people are actually watching.
The key takeaway here is that shaming people for their sexuality is harmful. It's bad for people's mental health to make them feel shame over something they have no control over, like how horny they can get. It's wrong to force people to suppress their emotions and make them feel guilty for not harming anyone. As Drew of Genetically Modified Skeptic once said; You can't shame someone out of feeling horny any more than you can shame someone out of feeling hungry.
Christianity often does this as a form of control by selling you the sickness and the cure; We are created sick and commanded to be well.
