Reddit reviews Passionate Marriage: Sex, Love, and Intimacy in Emotionally Committed Relationships

Maybe try reading "Passionate Marriage: Keeping Love and Intimacy Alive in Committed Relationships"by David Schnarch. It was recommended to me here in this thread by /u/amalgamator and my wife and I found it exceptionally helpful when it came to incorporating this word into our bedroom fun. You can check your library for it or here's an Amazon link where you can buy it. (not a referral link).

Specifically I recommend looking into Chapter 10. The chapter is called ^(Fucking, Doing, and Being Done: It Isn't What You Do, It's the Way You Do It) and even just the first few paragraphs of that chapter are an excellent read to experience alongside your spouse. Good luck to you!
