My clit is completely covered, to the point that even retracting the hood and pulling apart the inner labia only just barely exposes the head. I guess that would make me C-6, though none of the pictures looked exactly like mine. (The closest is picture #5 if you count left to right across the C-6 line, or the first picture on the second row of that line.)
I was circumcised, but my clitoral hooding was formed from leftover urethral tissue after it was removed from the penis; one side effect of this is that the inner portion of my labia minora and the hood are both light pink mucosal tissue as it is in cis women. My surgeon was Brassard.
