I don't know, don't care. The people in your scenario sound like low lives.
The only thing I know is that if a man cheats he:
Shouldn't do it on his own doorstep.
He should make damned sure his wife never finds out about it.
He should not embarrass his wife so that their social circle finds out. Leaving her no option but to take action.
He should use contraception.
He should not be such a pathetic wimp to upset his wife by confessing to relieve his 'conscience.'
He should own his infidelity and keep it well apart from his marriage.
He should be emotionally mature enough to know that his wife and family have a million times more worth than getting his dick wet and enough experience with women that he doesn't fall in lurve cause another woman touched him.
He should know what goes on tour stays on tour.
Trouble is that most men are such losers who don't venture into the next town for months on end that the only women they can cheat with is the pub, er, woman of low sexual boundaries.
