"He uttered a curse that startled her with its foulness, and ..." — Lisa Kleypas quote meaning

He uttered a curse that startled her with its foulness, and gripped her head between his hands, forcing her to stare at him. His voice was savage. "For twelve years I have been in constant torment, wanting you in my arms and believing it would never be possible. I want you for a thousand reasons other than your legs, and...no, damn it, I want you for no reason at all, other than the fact that you're you. I want to shove myself deep inside you and stay for hours...days...weeks. I want morning and noon and nightfall with you. I want your tears, your smiles, your kisses...the smell of your hair, the taste of your skin, the touch of your breath on my face. I want to see you in the final hour of my life...to lie in your arms as I take my last breath.
