“How does one identify love, lust, and desire?.. For sake of structure, let’s set out to define all three terms. Lust if straightforward sex. Great sex. It’s a chemical energy fused with unavoidable attraction that makes cheeks flush and panties moisten. Love happens when great sex finds best friend, when compatibility and passion lock in stalemate. But desire? Desire is a tricky, fickle, little bastard influenced by a vast array of things such as competitive nature, insecurity, and power struggles. Desire is a misery wrapped into a furious moment of flashing eyes and frustrating patience.”

Just a random quote I found.
