All those nuns in their convents, covering themselves with a sheet so that God couldn't see their apparently shameful naked body, had evidently missed the point of the lecture about God seeing everything, everywhere, always - it's quite funny when you think about it like that ;-) There is no need to be shy about your naked body, although if you wish to be, then that should also be ok. As someone said, "you don't have to be naked, but you can be naked if you wish". The point is always to have the choice.
