Sara, as usual you have a sane approach.
Men and women think differently.
If other married men are watching porn and if it is not affecting their married life negatively, let them do it. It does not cause a revolting feeling in my stomach thinking what or why other men are doing it. I think it is pretty normal for men to watch porn.
On the other hand, I do get sickening feeling when I see women watching horrible soaps on the TV and I think that to be sick.
Someone asked what if you catch your wife watching porn. I completely respect my wife’s individuality and never sneak on her. never. She is my wife and not my slave. Whatever she does in her own time, is her own choice.
