If I had to choose between having someone physically faithful to me or having him committed to my preservation, I would opt for the latter because there is no doubt in my mind when I see couples at parties selling each other out which is the worst offense. Physical fidelity is a lovely thing if someone feels that way about you willingly, but relatively meaningless of you exact it for a price. And while it is easy enough to be faithful for the first five or ten years, it is more difficult by twice each year after that, so women as well as men are finding it hard to do.
