How do you feel about your partner watching p*rn.

I was talking to a group of friends (straight couples) and majority of them said that they feel like their significant other is cheating when they watch porn. Personally, my girlfriend and I , very so often watch porn when the other person isn’t in the mood. And recently , we even tried watching porn while being intimate (didn’t work out, we were to distracted that we didn’t even pay attention to the tv at all lol). And honestly , I prefer my partner watching porn rather than going out and cheating if she has urges and she says the same for me. How do you guys feel about it?
