It would fall under Compulsive Sexual Behaviour Disorder[0] in ICD-10. [1] Pornography Addiction as a unique pathology is still not recognised but the issue is still young. We can see that it's an issue in that more than half of US divorce cases mention compulsive pornography usage. [2] You can read more about Pornography Addiction and what I mean by that over at Wikipedia. [3] You can see support groups for self-ide…
Compulsive Sexual Behaviour Disorder is not an addiction. The Wikipedia article that you cited begins with the following sentence: “Pornography addiction is the popular but unscientific[5] application of an addiction model to the use of pornography.” [5] Science Stopped Believing in Porn Addiction. You Should, Too. https://www.psychologytoday.com/us/blog/women-who-stray/2018...
Behavioral addictions are acknowledged in DSM-5 although this does not extend to compulsive sexual behavior at this time due to insufficient (yet growing) evidence to suggest similar neurophysiological mechanisms for a clinical textbook to label it as 'addiction' [0][2].
A recent review article breaks down the differences from gambling which is considered a behavioral addiction in DSM-5[1] and had not been in prior editions.
Whether or not CSB/hypersexuality is an 'addiction' in the medical sense is controversial amongst medical experts and essentially interchangeable with what a layperson considers to be an addiction and it is therefore very reasonable especially noting the overlap of salience, conflict and relapse[1].
Although there is insufficient evidence at this time to conclude either way whether diminished satisfaction has a similar mechanism to tolerance or lack of control has a similar mechanism to withdrawal there is also no strong evidence to support the argument that CSB is not an addiction and consequently they are currently treated as separate entities.
The pertinence of this is to not conflate conflicting/controversial expert opinion with generally regarded truth and therefore stating that parent is 'wrong' for believing it is addiction when many experts share the same opinion[3].
