I agree. But porn directly targets sexual behavior and response. It's the sugar soda to obesity.
But to singly focus on it would also be a mistake.
I agree about the porn thing, but I'd argue that is not so much one of the major issues surrounding it so much as teens not having sex at the rates they used to. More teens are entering college as virgins, men aren't being taught how to navigate social/sexual relationships by their fathers or friends, media content online holds greater value over real personal relationships, and frankly videogames nowadays have all but turned into time wasting gambling. I mean if you put a weak willed person in a room with any vice they'd want, they're gonna fail. And we're packed to the brim with vices. Now how do you expect any impressionable young man growing up to not become jaded because dating is bar none more difficult than it has ever been? Not only that, the fear of getting the girl pregnant and she keeps it or divorce. I feel like with all the stories about how men appear to get the short end of the stick oftentimes, it's led to a jaded understanding of the system.
