Which of the following would make you happiest?
Not a single one, and that's exactly my point! These propositions are based on treating a person as a thing used to further self-gratification, not a partner taken "for better or worse". A successful relationship is based on respect, understanding and love. The physical pleasures enhance the relationship, they complement a strong basis in love; they are not a substitute for it. What happens after a baby comes and nobody can get enough rest? What happens when your or your partner's health fails? What happens if there's a layoff at work, leading to stress and tough financial times? What happens when curves sag and muscles turn to flab? When hair turns grey, or falls out? When your teeth are soaked in a cup overnight?
Would you prefer that seven years later you get the call saying "He says I'm TOO FAT and that I'm TOO BORING and I think we're NOT IN LOVE ANYMORE"?
We all grow older, we won't be young newlyweds forever. That's why we need to value what a person is inside, not what shows and happens on the outside. Ask the Beatles.
