Love comes before sex. A willingness to put another first in our lives. So if we love God we put Him first. And in Loving Him, we can put another person first. Love doesn't allow cruising to find someone it can use for awhile.
Love is more than physical attraction.
Love wants to give to one another and not merely take. Love doesn't let us disobey God. If we say we love God, than we desire to do His will. God's will is that a man marry a woman. He created Adam and Eve and not Adam and Evan.
