The simple truth is tying a man to the bed posts isn't going to stop him from straying. While a healthy conjugal relationship is important to sustain a marriage, a marriage based on it alone may not be sustainable. I would think it also takes some bit of chemistry between two people and brains (in the head above the shoulders) in both individuals for a marriage to work out. Or to somewhat work. Otherwise, how do you spend the after-hours ? Let alone a lifetime. Forget the vows.
It also makes me wonder about the wives. Setting a standard higher than a first-class prostitute is kind of heavy duty. Where would they be deriving their syllabus from for teaching the lessons they must learn ? Alluring and Obedient Wife 101 must be real sexciting then. I'm curious, really.
Well, I guess the club members got to be careful when they aim to be better than a first class prostitute - some sexual acts are deemed to be against the order of nature in this country. Just look around.
