I'm probably a bit different. I do not like porn in the background at all. First, I tend to only view porn myself only to see something different (think kink, spanking or age play, etc.) or get a new technique or two (think Phd level handjobs

).
I feel that the man that I'm with is the ultimate viewing pleasure.
And I tend to really focus on the person in the room and having on porn would be a distraction, unless we're on some lengthy visit or date.
If a man wishes to bring porn, we can watch it if he desires. Having porn in the background wouldn't be a personal preference at all although it can, at times, be very hot and arousing.
