Thanks for the rare bit of sanity on this thread. We have it from Our Lord Himself:
"You have heard that it was said, Do not commit adultery. But I tell you that anyone who looks at a woman to lust after her has already committed adultery with her in his heart. If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell."
If I actually followed that rule, I would have become blind long ago.
