DON'T BEAT YOURSELF UP POPPET.

Truth is your partner has more then likely been into pornography & more before you came along. What you don't see is this is "his" sickness, not yours.
When a guy gets into pornography to the extremes, it becomes an addiction & yes, people can get addicted to porn as well. But be careful, I know from experience, with some, adult porn becomes boring & sadly this is where child porn can come onto the scene.
I'm sorry if I just freaked anyone out, but the reality is we are living in a world of sexual sickness to & porn don't help it!!!
Take care Poppet, am sorry you have to deal with it to
