Pornography is corrosive to relationships.
Much of the sex portrayed in porn is a reliving of childhood sexual trauma. If that's what you're getting off to that is what you will be attracted to.
When a man watches porn they train their sexual response to seek constant novelty. This makes monogamous relationships much less appealing.
Porn addiction is rampant in society and it's hard to get away from it because marketers are using sex to sell products everywhere.
I don't write any of this to pass judgement, but to illuminate a problem that many many struggle with.
If you are in the habit of watching porn I'd like to challange you to go one month without it and see how you feel.
