>I cuddle with a friend (who’s also married.) Funny enough, I still have sex with my wife.

Yea, dude, the fact that you need to justify it with "funny enough" that you have sex with your wife shows YOU know it's sex adjacent. YOU have that association.

>and we classify this as not cheating

I'm sure you two do rationalize your cheating with each other. I can "classify" the sun as a bright ball of cheese to myself if I want, but we both know it aint.

>It can be very affectionate at times, just never sexual.

Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiight.

If it's not cheating, you have nothing to hide, and will be more than happy to make sure your wife and her husband feel the same way. Why go to reddit instead of your spouses for another view?

Oh right, because you're cheating and you know it.
