Here is the biggest kept secret of them all (kept from the deviants and fornicators), sexual pleasure in a monogamous long term marriage increases the longer you are together. That's right, that older couple still in love is doing 1000× better than the weirdos who demamd more and more freakazoid accessories to try to experience something. God's plan and Word will never lead you astray. You can stand on it, like a rock in a storm.
