What insight, specifically? You make big claims with no citation, and when asked for more info, you dismiss those questions. If you’re interested in helping others understand the insights you claim to have, bring some details to the table!
I’m pretty curious about the topic, and this is an inquisitive community in general. Unfortunately, the way you’ve presented your position is not helpful, especially for a group that tends to demand scientific proof or at least a well formed hypothesis.
Forget about the porn for a moment. Read it first as online habits programming the mind. When you visit certain websites, the content and algorithms tend to program the user's mind. You can see it with Facebook influencing politics and such. TikTok, etc.
Now bring in the porn websites and you will realise how it programs the user's mind in a similar way. Eg. After some time, some people will exhibit cuckold, submission/domination, incest behaviour in real life. Some will look at an older woman and not see a mother but a milf. Hope you get the point. I don't have any scientific proof but I used to be a porn user myself. You are welcome to research the subject further if you are interested.
Referring back to the parent comment, as the stimulation of vanilla porn becomes boring, the user will need to watch more and more hyper stimulating material. Not dissimilar from a drug user. Some lose the interest in regular real life sex altogether or need to incorporate their porn habits into it.
I don't mean to generalize so if you don't think it applies to you then move on, but if you are interested in self improvement then tread these waters carefully.
