I've been happily married for almost 18 years and have literally never touched another woman. (Okay, a few hugs and pecks on the cheek.) I also don't doubt that if a woman made a play for me and was obvious about it, I would succumb. Is adultery worth it? Is the experience of a new lover as great as I imagine? Or do you feel yourself stepping outside of your body, looking at the two of you and remarking, "Gee whiz, you're really doing it"?
