"Well, in terms of individual consequences, what we find is that, more often, there's a connection between viewing pornography and experiencing depression. But we found it's really only for men who are violating their own moral beliefs when they're viewing it. In other words, it's not necessarily that porn makes you depressed. It's watching porn when you've already said that that's an immoral thing and you don't want to do it. That can lead to guilt and shame that makes you feel crappy about yourself, that you are immoral, that you're violating something that's deeply held and sacred." -- Samuel L. Perry, author of Addicted to Lust: Pornography in the Lives of Conservative Protestants, interviewed by Isaac Chotiner in The New Yorker, 2019-05-03 [thanks to twistedchick for linking to this earlier]
