“The word ‘naked’ is a translation of the Hebrew erom, which is used to describe a state of being stripped or vulnerable, and is without sexual connotation. 

[…]

Called out by God, Adam says: ‘I heard you in the garden, and I was afraid because I was naked; so I hid.’ His nakedness, erom, merely implies vulnerability. Perhaps Adam and Eve hid from God not because they were suddenly prudish, nor because their disobedience had been found out, but because they realised their fragility and insignificance. They were exposed, not as sexual beings but as mortal ones.”
