Clampers girth focussed. Also lengt from clamping.
If you clamp, the head is also expanded to its maximum. That means the blood is not pushed only sideways, but lengtways also.
Length gains while clamping won’t come from the ligs, but from the tunica. It’s harder, but I think length gains from clamping are underestimated.
When you have had your max length gains out of your ligs, it is possible to work on the tunica whilst clamping and get extra length gains, beside’s the girth.
If you flote a balloon it doesn’t expand only in girth, but also in lenght…
I, can, I can, I can not, can not compute..
