Bib, lig stretch question...
Bib, based on the job the fundiform and suspensory ligaments have and how they work/attach, etc., do you think erect stretching has any potential?
Take the suspensory lig, it attaches to the facia of the tunica, and as the tunica expands and erects, it helps lift it into place. When the penis is at maximum expansion, it would seem the ligs would be well stretched. Wouldn’t pushing downward on the head/top of the shaft as far as possible in this state serve to further stretch the ligs and facia pretty effectively? You could do the same thing side to side, hitting many angles to work all the ligs.
Of course the key would be maintaining a 100% erections, but with the proper application of porn, that shouldn’t be an issue :)
