The Curse of Desire in a Marriage Covenant

In the marriage covenant, a man gets his like pleasure from desiring. And a woman is pleased by being desired, right? So when sin gets in there and disorders everything, that's what you see on pornography. In Genesis three, where does the curse land? It's it's basically your desire will be for your husband, but he will rule over you. The same connotation later in the second text,. God warns Cain, sins desire is for you, but you must rule over it.
