Ouch! Cheating is never a good thing. No one likes or too often is willing to accept being cheated on. I fear you misunderstand the implied cheating is more a fantasy than a reality. A wife goes out to meet a lover or even a bull it may be treated as cheating but the reality is it was well planed by both . Without that the divorce rate would soar . Sex games, fantasy, open relationships can all be a plus to a relationship but only if they are open without any real deception or lies.
