I think the TV was only one once while having sex with my current boyfriend. We were just watching TV and chilling and the mood struck us. It was some Loss Prevention show. It was a little weird because I'd catch him watching it a few times while still pumping away at me, haha, but he still took care of me.
All the other times it has been off except for the last two or three times we have had the laptop on the bed with porn playing.
With my exes... it was really 50/50.
