For sex, to me, means the whole of the relationship between man and woman. Now this relationship is far greater than we know. We only know a few crude forms—mistress, wife, mother, sweetheart. The woman is like an idol, or a marionette, always forced to play one role or another.... If only we could break up this fixity, and realize ... that a woman is a flow, a river of life, quite different from a man's river of life: and that each river must flow in its own way, though without breaking its bounds: and that the relation of man to woman is the flowing of two rivers side by side, sometimes mingling, then separating again, and travelling on. The relationship is a life-long change and a life-long travelling.
