Lust is a big theme in Proverbs—and it's directly related to adultery. Proverbs supports fulfilling your desires, but not in letting those desires lead you outside of the prescribed areas of family life and social life. You need to fulfill your desires within the moral law, and—by violating one of the ten commandments—Proverbs makes it clear that adultery, and the lust that fuels it, don't do that. They really mess up everything.
