I think about this a lot because I'm in a general recovery group for substances and addictive behaviors and it fascinates me.
Part of it is because porn is a hyper dopaminergic stimulus. There's some evolutionary circuitry in your brain designed to release a shitload of dopamine when you see an opportunity to mate because continuing your genetic line is literally the most important thing an animal can do. But being able to just trigger that response any time you want, for as long as you want, is a high we're not evolved to handle. I mean shit, the whole premise of gooning is putting off an orgasm so you can look at porn for longer, so it must feel pretty fucking good if people are saying "nah I'd rather not cum right now."
Part of it is novelty or escalation or whatever, where people get accustomed to the dopamine and need more and more tabboo shit to feel the same high, like with drugs or gambling. And just like with dopaminergic drugs and gambling, I'm sure it makes everything else feel worse in comparison and it's all you want to do.
But the really fucking insidious thing that I didn't realize until I read the Goonclown leaks is that just like drugs and gambling, some of them treat it as a coping mechanism or a form of dissociation. Like, it's not just "I'm horny must coom," people turn to it the same way people turn to drugs and alcohol, as a way to distract from or escape from things in their life. I remember reading something where someone pointed out that they were opening the incognito window before their dick is even hard, which indicated to them that it's not a biological urge that's being sated, it's something else.
I remember hearing about some guy, either on Radiolab or This American Life, who started an antidepressant that affected dopamine reuptake probably, and claimed it made him hopelessly addicted to porn. He talked about going on the dark web and repeatedly downloaded and deleting and redownloading the same child porn and beastiality porn, knowing it was wrong but unable to stop. I take it with a grain of salt because he said that as a legal defense, but it struck me as extremely similar to another woman who started a Parkinson's drug that also affected dopamine (because dopamine has a lot to do with motor coordination) and she became hopelessly addicted to gambling, and talked about buying groceries and then sitting at a slot machine for 8+ hours, fully aware that the groceries next to her were rotting but unable to walk away. I don't necessarily buy a pedophile's claim that an antidepressant made him a pedo -- or I guess that an antidepressant made him a porn addict and the escelatory nature of addiction made him a pedo -- but it's telling to me that the story is so similar to that of someone with an addiction to a dopaminergic behavior.
I'm a pretty uncanny caricature of a lolbert but if there's one thing I support the outlawing/censorship of it's internet pornography. It hasn't done anyone any good ever and leads to a lot of fucked up children who grow up to be fucked up adults who fuck up more children and the only reason people don't research it or talk about it is because they're coomers or gooners or (((pornographers))) or getting paid by (((pornographers))) or have been brainwashed by (((pornographers))) or wear the same hats as (((pornographers))).
tl;dr behead (((pornographers))) and Never Goon.
