C.S. Lewis also covered the subject in his book, the "Four Loves." This would be a useful commentary on the issue.
Lewis expresses much better than early Augustine. He did have a few things from his days with the Manichees and as one who was living in sin with a mistress, but even in City of God, he was trying to work through them. Augustine expressed in City of God that it would be better to separate lust from procreation, so that it would be solely an act of will and not desire, but that was because such desire is so often wrongly expressed.
There is nothing wrong with me desiring my wife and having an active love life. There is a lot wrong with me doing that with every person and thing I meet. In todays culture, it is seen as "repressive" to not screw any and all comers. That isn't healthy, any more than if I ate every piece of food that I could lay hands on.
