The one charm of marriage is that it makes a life of deception absolutely necessary for both parties.
—Oscar Wilde, The Picture of Dorian Grey
Most of the time, if a man and woman want to have a love affair and if they are both serious about keeping their affiliation unknown, it’s possible to do so. It’s much more possible in a large city than in a small town, it’s much
more possible without children than with them, it’s much more possible if only one of the parties is married. Nevertheless, it can be done and indeed is being done all around you all the time. Linda Wolfe, in Playing Around: Women and Extramarital Sex, describes her surprise at discovering that her West Side Manhattan neighborhood, which appeared on the surface to be a world exclusively of mothers and children, was in reality a world shared extensively with male paramours, some of them fantasized, others quite real. Just in her small apartment building alone, four of the eight married women with small children were having affairs.
Sometimes, the cuckolded husbands and wives involved are very naive; more often, they have decided at some level of consciousness that they would rather not know. Sometimes, the participants are skilled at maintaining a suitable image so that there is no reason for suspicion. Sometimes, they are skilled at dispelling any suspicions which do arise.
And sometimes, of course, they eventually just don’t care and gleefully toss cats out of their bags and let them land where they may.
