mm : It's true, at least the unpleasant surprise had an upside. 🙂 With that said, the surgeon had no problems with anyone except the woman who was under 1" erect (she got a skin graft) so its also not quite as direct a correlation as length = depth. I think there's some extra stretch to the skin or something. In fact, some of it *must* be about the skin itself contracting/expanding, because there's no way anything regrew from scratch that quickly.
(I also went to Brassard, who tries for 5.5"-6" of depth pretty consistently, so it's possible the additional skin got me some nicer labia or whatever...)
