If you cant go naked and accept the added risk of damage then get a case. You can barely notice that, hardly worth giving it any more thought. Remember, its just a phone.
I pay insurance through my carrier that covers accidental damage I do like naked that's why I have insurance guess that's the risk could have been worse
I would just slap a bumper or case on it. My white i5 is still naked. If/when I drop & damage it cosmetically, I wouldn't claim anything unless the screen shatters (or it doesn't work).
