When you put on a porn video just to have playing in the background while you're doing something else but once it starts you're like, "Actually, I wanna pay attention to this one..."
I don't think my wife ever saw porn from her unique reaction years ago, vhs days. We hadn't been married long when I told her of a friend's huge collection. It wasn't immediate but a day later or so she brought it up again and I borrowed a couple. Once the movie started she was giggling about the silly story and how bad this was and that was and boom a guys big dick starts getting sucked and she shut up and watched. She wanted to put it on right at bedtime and get all warmed up then off to bed. Funny, she thought watching it while we were doing it was uncomfortable.
If I watch porn it’s not for some background noise and images, there’s a purpose otherwise it doesn’t get put on the occasional visual boost
