Hey, I got your attention. It seems that we in evangelicalism are typically mum about the goodness of sex. We are either talking about it in very generic terms or saying, "be careful STAY AWAY FROM IT!" As I was preaching through the Sermon on the Mount yesterday and going through Jesus' explication of Kingdom ethics regarding lust, I couldn't help from drawing on the idea of good "lust" in the Proverbs.
In Proverbs 5:18-20 Solomon lays out all the alluring physical attributes of his bride and then says we are to be "intoxicated" in the love of the wife of our youth. The Hebrew verb for "intoxicated" (ESV) is "shagah" and means "to err or go astray." Strong language. So it seems a solution for lusting is not to conquer it but to re-direct it. Conquering it (in the absolute) seems to smack of stoicism and monasticism.
