I do not regard sex as part of marriage?

So it's okay if he USES other women as long as it's not you? And, what if he followed through with your suggestion and fell in love with another woman? If a sex free lifestyle is your choice, you should remain single. Not only is sex a part of marriage, it's necessary for good health and I feel you shouldn't marry at all if it is your intent to deprive a spouse because unless he's impotent and willing to live celibate, this arrangement is doomed to fail.
