It is really simple. If you kiss another woman and you hide it from the wife, YOU must consider it a cheat. If SHE would freak out if she saw it, It is a Cheat. If you freak out if she kisses a guy, then you gotta make the call.....

Lets face it, you find a crazy kinky type who is into open marriage and you are into it, than doing a horizontal bop isn't going to be cheating if you still come home together. That tho take a special type of person to do that and still have a relationship. Personally, I kissed my wife's best friend in a restaurant with her date and my wife there and got away with it. The BF didn't like it, but my wife was laughing like hell. Sometimes it is all context....
