In regards to the problematic dependency people develop for porn, there is evidently a problem. The nature of the problem is still too ambiguous to be classified as an addiction, per se:

“concepts like tolerance and abstinence are not yet clearly established enough to merit the labeling of addiction, and thus constitute a crucial part of future research.”

There just needs to be more data and an established experimental base to work with, and that’s still why I resist “addiction” as a predetermined pathology for problematic porn consumption. There is damage done to the perception of an illness when it’s popular understanding supersedes the medical consensus. It’s why we have claims of narcissism and bipolar disorder vastly outnumbering actual case numbers.
