Well, the answer is yes. But your question is odd at best. It is like asking if the Bible says anything about the need to see a dentist. Or, does the Bible say anything about the need to take a vacation and say go to Disneyland. Are all things invalid if not specifically, categorically, mentioned in the Word of God? 1 Cor. 7:3-5 talks about the human sexual need and the obligation of the spouse to satisfy that need. The specific need is not identified but can be safely assumed to be inclusive of procreation and recreation. Yes, the Bible is an advocate of marital sexual pleasure – its pursuit, its conquest and its glory as all subject to the Glory of God.
I grew up never hearing about sex at all, only that you weren’t supposed to do it until you got married. So for years and years you get told that sex is bad and then all of a sudden one day it’s supposed to be the greatest thing ever.
That didn’t sit well with me and I’m sure I’m not alone.
