'When the physical encounter of men and women in the intimate act of intercourse is not an expression of their total availability to each other, the creative fellowship of the weak is not yet reached. Every sexual relationship with built-in reservations, with mental restrictions or time limits, is still part of the taking structure. It means "I want you now, but not tomorrow. I want something from you, but I don't want you." Love is limitless. Only when mean and women give themselves to each other in total surrender, that is, with their whole person for their whole life, can the encounter bear full fruits.'
Henri JM Nouwen, Intimacy, p.32.
