only fans & SO’s subscribed

So I got curious about this topic.

I was listening to a podcast about them being ok with their significant other watching porn but not ok with them being subscribed/ paying a monthly fee for a certain persons nudes and explicit content to view everyday and/or get off too. For that person it’s considered cheating and makes them feel very insecure. The problem they have with it is more their significant other paying actual money to pay for that specific person because they find them so attractive.

what are your thoughts on your bf/gf (wife/husband) being subscribed to only fans and using it to get off? and actually paying extra for a nude they send only to them exclusively.
