I think porn/sex addiction is an underdiscussed topic. A lot of people will say it sounds stupid but it's probably up there with alcohol and gambling. If you use the internet, it's almost impossible for something suggestive to not pop up on your feed (especially on twitter.)
I've seen a lot of people downplay minors have unlimited access to it, but I don't understand how you couldn't view that as a problem. Young boys developing have access to the nastiest content available before they even understand what they're playing with. This isn't back in the day when you stole a magazine or rubbed one out to a bikini photoshoot or something.
It also impacts our social dynamic. We downplay it, but the majority of men's interactions with women are built off lust. If that urge is being satisfied elsewhere, that limits the interactions men will pursue with women.
Additionally these industries are clearly targeted to manipulate lonely men (some who are at the bottom of the totem pole). We have AI sex bots, of girls selling "girlfriend experience", of girls scamming, etc. You can say it's pathetic all you want, but to ignore the fact that it's a problem is insane. And since these industries empower women, we most likely won't hear people detail how it harms are particular group of men.
TLDR: Sex/porn addiction should be treated like other addictions. It's probably more dangerous because it's accessible more freely. Just like with any other addiction I'm not saying the user isn't accountable, but it's still a problem we need appropriate resources to handle
