Agreed. He was a man of intense choices, but felt his sexual urges were difficult to control. I think his time with the Manichaeans also greatly influenced his body/spirit dualism and his theological success against the views of Pelagius probably made all his other views (including sexuality) more credence. Furthermore, if it wasn't for Saint Augustine, we probably wouldn't have the concept of Original Sin, as we do today, which is highly sexual in nature and form. So....thanks a lot buddy.
