This gets into the meaning of love. And love isn't sex alone. And love isn't just what one person feels.
Joseph Campbell in 1986 regarding such a marriage of true ego confrontation: "Well, the real word, I think, is 'ordeal', in its proper sense. That is the submission of the individual to something superior to itself. The real life of a marriage or of a true love affair is in the relationship, which is where you are, too. You understand what I mean?"
