“How can I explain these things, so obvious, and yet so invisible to those who think that “it’s all about sex”? Difference of sex makes a difference, but what kind? Perhaps I should leave it at this: To a man, women seem to glow in more hues than men do. In different ones too. The spectrum is wider, the world has more color, because of their presence in it, especially the presence of the beloved. Of course there are certain things which a normal man prefers to do with other men, like playing tackle football. Yet the very light and air seem to change when a woman leaves the room, and all men know it. Obviously this fact is connected with her bodily presence, but it isn’t about imagining her naked.” - J. Budziszewski aka Professor Theophilus¹

An excellent quote by one of the better Focus on the Family authors.
