Curious cut guy here. When the skin returns to home plate, do you feel any sort of "pop" or sensation that it has returned to it's normal position? Especially if your skin completely covers over the head of your dick?
As far as I'm concerned, I perceive the "sliding" or "movement" of the skin forward or backward (depending on whether the glans is being covered or uncovered) when this is done.
However, if the penis is free, i.e. without touching anything, I can't always tell (without looking) if my glans is completely uncovered or covered.
Evidently, in addition to feeling the displacement of the foreskin, I can understand if the glans is exposed only if it rubs on something...
