[Before Adam and Eve sinned] there is every reason to believe that, in their state of innocence, they looked admiringly on the physical appearance of the other. But [once they sinned,] this look was different. It could see a deeper nakedness, or at least the one being observed felt more exposed. The eyes of the other person became piercing lights, seeing body and soul, seeing the ugliness of sin. The feeling of being exposed, once completely foreign, was now the only thing they felt. They were seen by the other, and what was now seen was shameful. Once admirable in their innocence and beauty, their souls were now grotesque.
