I wouldn't want either of those, but if I had to pick I guess I'd go with B, because then it's over with. I don't like watching the same porn vid more than a handful of times because it gets old, and also having it be of my parents would just make it weird and uncomfortable.
My turn:
Would you rather:
A: find out your significant other was secretly recording your sex to post to only fans (or other paid porn sites) and was making a ton of money?
Or
B: find out your significant other was secretly recording your sex to post to only fans (or other paid porn sites) and absolutely nobody was watching?
