Some people do start threads just to get attention...this one smells of such.
There are some people that do get off on 'bagging' married women.
Those of the rest of humanity that are sane enough, understand what both sides of 'The Golden Rule' are like, and simply wouldn't do it, because they wouldn't want it done to them, and they have enough wit about them to stop and imagine what it feels like to be betrayed in such a way by your own wife or girlfriend.
