Skip the rewiring panic, look at the guilt

"Porn rewires your brain" is everywhere. The evidence behind it is thin, and the field is still arguing. In one EEG study of 122 people, which reads the brain's electrical activity through the scalp, problem users with high desire reacted less to sexual images, not more, as the rewiring story would expect. Evidence: worth trying That's one study, and it's disputed.

What holds up better: in a review of the studies, feeling hooked on porn went with a clash between what people do and what they believe, not only with how much they watch. Evidence: decent

So the useful question isn't what it's doing to your brain. It's whether it fits your values, and whether it's taking something from your evenings or from your partner. If it is, that's reason enough to change it. No brain science needed.
