I think many men have porn addictions. Is it right? probably not...could it be worse...yes. I personally have struggled with it but after getting caught I quit...it was hard because it was part of my life for many many years...I never though much about it or put much importance in it but I saw it hurt my wife so I stopped for her.
Not sure how to handle confronting him...if you are in joint counseling or anything like that I would do it there.
Interested in what others say....
