The Hormones are meant to say to us "do not go exstinct!" and "be frutiful and multiply." The problem is they were programmed in us in paradise in our ancestors Adam and Eve before they sinned. We now live in a world given to futility and that is fallen, and so it is not easy to harness these hormones without sinning. It has not helped social norms and academia and even economics has pushed the ability to have a family out so far that marriage is not something common in mid to late thirties and even late forties! Whereas in the Bible we see people marrying young and able to use their hormones under the covering of matrimony. It's a puzzle, we do not condone sin, but society has made it so being able to use those feelings free of sin is rarer.
