454. 9. A lust to fornicate is more serious as it verges toward a lust for variety and toward a lust to deflower. The reason is that these two lusts are augmentations to adultery, thus making it worse. For there are milder adulteries, serious adulteries, and more serious ones; and each is judged according to its opposition to, and thus destructiveness of, conjugial love. We will see in chapters to follow regarding these lusts that, when confirmed by actual deeds, a lust for variety and a lust to deflower wipe out conjugial love and sink it, so to speak, to the bottom of the sea.
