Prayer as an aphrodisiac

I know a lot of religious people might find the involvement of God in your sex life as antithetical, but the way I see it is that God himself created sex! My husband and I have a habit of praying together at night. Sometimes, hearing him pray with sincere gratitude and concern for me, for our kids, for other people -- it just warms my heart so much that I want to kiss him! And sometimes that kissing leads to other things... and I think God grants us our privacy, but doesn't consider it wrong that it started with prayer!
