> If he is actually a bi-furry with an understanding with his wife on 'affairs', do you think he'd say that?

Yes, and it would have helped. These are entirely different stories:

"My wife and I have a non-traditional relationship and would prefer to keep the specifics private, but no harm was caused by my actions."

"I was unfaithful to my wife. My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry."
