I think the real question here is if Isabeau's husband lived out a sexual fantasy with another woman because she was unwilling to perform a certain sexul act, how would she feel? She would feel betrayed, hurt, and mad as hell. I see no reason why her husband wouldn't feel the same way.
As for those preaching how "you have no right to judge someone," I got news for you, you little (or oin some cases not so little) self-righteous hypocrites - I can judge anyone I want in any way I see fit. That's the magic of freedom of speech, baby. Just because you think it's okay to cheat on a spouse (although I think the operative word here is husband or man) doesn't mean everyone else has to subscribe to your moral bank.
On a side note, I seriously doubt if a man came on here and posted about his tryists it would receive the same warm, encouraging welcome. I think many females here would be calling him a cad, a bastard, a liar, etc.
In several states, adultry is a punishable offense in divorce court. Isabeau better pray here husband never figures out what she did, because if he does, he has every right to go after her legally, and he could use this very thread for his own legal benefit.
