If nakedness is improper and something to be ashamed of, why did God wait until Adam and Eve had eaten of the ?

Before the fall, man's mental powers were under complete control. the intellect, imagination, our pions,etc. After the fall, those mental power went haywire. You know how rampant the imagination is... you were supposed to be studying for a test and an hour later you find your mind entertaining all sorts of images that cross the mind. Well, this also, included the pions and all other pwers of the mind. So, after the fall, the first thing Adam and Eve noticed was their nakedness. their lusts were out of control. So, now it is proper to dress ourselves appropriately, so as to not tempt others to sin. The human mind has weakened severly. So much so, God doesn't even allow us the use of approximately 90% of our brain power. Because we are so damaged and without regulator. Look at the evil men do now... So nakedness in and of itself is not evil. it is our minds.
