Will Ley tell xHamster customers that every study ever published on males (about 70) links more porn to less sexual and relation satisfaction? Will Ley tell them that all 52 neurological studies on porn users/sex addicts report brain changes seen in drug addicts? Will he inform his audience that 50% of porn users report escalating to material they previously found uninteresting or disgusting? Somehow I doubt it.
This doesn't look like mere religious fundamentalism to me, it looks like there is a shitload of research that supports the idea of excessive porn use being harmful. Is it addictive in the sense that heroin is addictive, no, probably not.
Porn is absolutely problematic but there's a difference to it distorting societal views and expectations around sex and whether or not it's addictive. Porn gets an interestingly unique bad rep. These are fantastic points to bring up to help center ones understanding of addiction medicine and porn's effects on society. Thank you for sharing the links.
He's citing valid results from actual research papers, but I think he might be presenting it slightly misleadingly, perhaps with an underhanded motive, by implying no one has any issues with porn. But the general conclusion from the article seems to be that porn itself isn't harmful or addictive, but that other factors can cause it to be harmful. If somebody is using porn excessively, then it's most likely because there's something else wrong, the porn is the result of the problem, not its cause. At least that was my take.
Gary Wilson's Your Brain on Porn is a problematic source. It's not a peer reviewed academic source and its citations should be taken with a pinch of salt. The tone of the website often appears downright unhinged, especially when discussing the work of clinical experts such as neuroscientist Nicole Prouse.
Neither APA's DSM-V nor WHO's ICD-11 recognise any addiction disorder related to pornography. While ICD-11 recognises compulsive sexual behaviour disorder (CSBD), the absence of a close fit to established addiction models has been remarked. On the other hand, there is a substantial cottage industry based on this pseudoscientific concept.
