The sexual relationship between a man and a woman is described biblically by the verb "to know". To know a woman was to be sexually intimate with her. By contrast "to lie with" a woman was just simply to have sex outside the constraints of marriage, and as such it was expressly condemned.
It is not good for a man to be alone. Without a woman a man tends to wander through life untethered and at loose ends, lacking purpose. This is what you bring to a potential relationship. It's why he's drawn to you instinctively. Your power is sexual in nature but its a kind of beauty that is more mysterious, more intrinsic, than a lovely face or body. Because you are the image of God!
God rests enormous power in the heart of a woman. The most valuable aspect of a man's being requires your permission, your reception of him. God makes a woman the prize to be won-a prize that is meant to go to a man worthy of you. She becomes 'the ultimate arbiter of a man's worth!"
