"Some men feel their masculinity can only be proven if they play out in their own life all the locker-room stories, smugly confident that what a wife doesn’t know won’t hurt her. The truth is, somehow, way down inside, without her ever finding lipstick on the collar or catching a man in the flimsy excuse of where he was till three A.M., a wife does know, and with that knowing, some of the magic of this relationship disappears. There are more men griping about marriage who kicked the whole thing away themselves than there can ever be wives deserving of blame. There is an old law of physics that you can only get out of a thing as much as you put in it. The man who puts into the marriage only half of what he owns will get that out. Sure, there will be moments when you will see someone or think back to an earlier time and you will be challenged to see if you can still make the grade, but let me tell you how really great is the challenge of proving your masculinity and charm with one woman for the rest of your life. Any man can find a twerp here and there who will go along with cheating, and it doesn’t take all that much manhood. It does take quite a man to remain attractive and to be loved by a woman who has heard him snore, seen him unshaven, tended him while he was sick and washed his dirty underwear."
