Most do so indiscriminately. What is unique to man is his ability to love. He can control his thinking and his actions so as to stay faithful to the one he loves. Sex, being designed by God, is not wrong in and of itself. Man will magnify, in his mind or estimation, an idea or concept above God.
Sexual obsession is nothing new to our generation.
But our generation must learn to guard itself on many fronts. Movies, TV, Internet, periodicals, music, advertising, and all other mediums use sex to sell their product. As a culture, we are what we think. Corporate America wants us to think sex. God wants our thoughts to be set much higher.
