Love is a mysterious thing. Not even Adam understood it. He saw woman and something was set alight in his heart. It was something about her that caught his heart. That's still true of love today.
True love is always more than an attraction to the persons physical body.
It has to do with something about the person. While love is of the heart, commitment is of the head. It is a conscious act of the will. Order in the church is established by God. It is fulfilled by the different roles that people play in the church.
