Porn addiction

Why do we get addicted to porn? Nowadays nudity isn't as exciting for most people, but varitey and change is. This is because biologically we are meant to have as much sex as we possibly can. thus our race will live on. People often fast forward most of a porn video because they "need" the more exciting part. It stimulates our primal instincts, this is why porn is one of the most addictive things on the internet. An ancient mechanic in our brain is telling us to get our natural rewards, like sex, being part of a community and food. Basics of survival. These have a higher addiction rate. For example tasty food with plenty of fat inside or hot girls give our brain more dopamine thus excitement. But too much dopamine can override our satisfaction threshold. For example if you give fast food to a rat, it will get fat. Not like natural rewards (dopamine) drugs and alcohol are only addictive to 10% of users, regardless of species. In the past, this mechanic was an evolutional advantage, like hunting and mating season. "get it while you can!" source: Gary Wilson "The great porn experiment" TedX
