All this to direct your attention to Roxeanne's answer in Belvedere's comment section:
"In The Screwtape Letters, C.S. Lewis said that Satan’s goal is to take normal, healthy pleasures and pervert them, so that we need ever more for ever less enjoyment in return. When you decouple sex from love, you end up working incredibly hard to replace the love component with physical pleasure and excitement, which must necessarily result in ever-increasing disordered activity. “Normal” sex becomes boring, not because it is so, but because it is so without love, without the underlying connection that constantly strengthens as the couple goes through married life."Yes, yes indeed. Beautifully said.
