point1) Logia have to conciously transform to avoid being hit. most learn to do it by reflex, and Caesar instead just never turns back. So if Luffy had no control yet, he wouldn't be able to avoid being bitten.

point2) to repeat? Luffy gets ripped apart by shockwaves; impact/reject dials, the Rokugan, and the like. If he ate 2 DFs, not even his rubber body could save him.
