Yaeger, I don't think the point is God not wanting us to enjoy sex with a spouse, if your talking about contraseption, I doubt God intended that we use it, there's someone in Genisis who is killed for not letting his seed go in the woman, there were other circumstances around that though. As far as I know the only instances in the bible where sex is mentioned between husband and wife is when a child was conceived. When a child is conceived it is a blessing and not a curse like some modern thought on it goes, this could have something to do with the cost and responsibility that goes with having children, and peoples general lack of responsibility.
