This isn´t your average question for a Thunder´s post but anyway:
When you get a full errection (this is for uncut people by the way), does the skin on your penis stretch back fully down the shaft, i.e. is the shaft long enough to make that happen, or do you have foreskin bunched up a bit against the glans?
I ask because my frenulum is still strong, and so holds the skin up there, and also because I´m not long enough to stretch the skin out!
My main question is, is it a part of the growth cycle for the frenulum to weaken considerably (almost disappear) and for the skin to be stretched more or less completely when erect? One way of answering this would be science, but another would be what happens when you get erect (if you´re uncut).
Any input would be welcome!
