You might be looking to much on the surface. Flesh might represent desire or gluttony.; not necessarily in a sexual sense. Life is full of temptations that will try to tear us away from what we want most. We give into our vices, our individual "Black spots." Black days are beginning because humanity has lost sight of whats we need and traded it for what we want. As for of the "children of the night" this could be a reference to vampires, as people will suck the life out of you if you can't hold your own.
