Cheating is entirely subjective and there is a lot of stuff going, especially in older couples. Cross exchange and sex parties are more frequent than you might think. There are a lot of places where you can go and have sexual approaches with strangers who are members of the club. All in all, it all comes down to the mutual decision of what is a "game" and what is actually cheating.

However, my own personal view of things is that our mind is not made so we are tied by a single one. This is a way of being we force on our nature due to the way our society is structured. Therefore, i am very lenient and i think "cheating" physically is just part of human nature, feeling attraction for others is normal and it can happen to slip down on that side a little. On the other hand, in a relationship where there is a strong emotive affection, physical betrayal can become harder to understand. I restrain myself from some people i know i have a thing for, cause my intent is to respect my counterpart. What's more important, in a relationship like that, feeling psychological/emotive attraction for someone else is the real cheating. That's in my own opinion, the only really inexcusable thing in a high-level relationship.
