There is a certain pleasure in ugliness. The example coming most quickly to mind is pornography, but all sin would fall into this category. The most terrible dilemma I face is that I hate the ugliness but love the pleasure of the body. Logically, it would be easy to say that the body must take second place- but the flesh is not logical. As in Romans seven, "That which I do not want to do, I do."
