This is why everyone says not to snoop unless you're looking for a specific piece of intel.
As for the "sickening positions" - are you referring to sexual positions? If so, does that information matter? Either you're willing to forgive cheating or not. There is a lot of judgement in your statement, not saying I don't feel for you because I do (nobody should have to hear about the specifics of the wayward spouse with their AP), but you may want to reflect and see if being judgmental could be a 180 for you.
I've seen a couple strategies on here about confronting a cheating partner, may want to look into those.
Take all of this negative energy and turn it into something positive. Best of luck.
