As a Christian, you must fight. You must fight hard to win against Satan and the temptations he puts in front of you. You are created in the image of God, and part of that image is to enjoy beautiful things. And because the female body is a beautiful thing, males enjoy looking at it. But...God tells us that there is a time and a place for everything under the sun (Ecclesiastes 3:1-8). The time and place for a man to enjoy a female body is marriage. That's it. No more. Nothing else. No exceptions.
