So it is in our HEART, not in our sexualness, that we human beings think and decide how to live - even if the decision is to indulge in venery of whatever sort. A man sees the complementarity of woman and man not through the eyes of lust but in his heart. Jacob's lust for Rachel distracted him from perceiving the virtue of Leah, a virtue to complement or complete his. It's in his heart, not through the lust of his eyes, that a man sees or learns to see the complementation of woman and man. If a man is 'homosexual' or has little lust toward attractive women, this is no obstacle to his perceiving woman as his complement or helper.
