I would say he is 8 NBP and 7.5 girth for sure, and along his whole shaft.
I can do it with pumping clamping, stretching with the vac hanger (did this yesterday and WOW I LOVED IT) and an ADS. Hanging will have to wait, as it hasn’t done anything for me recently.
It would with the vac but my sleeves simply just suck too much skin into it and it becomes ineffective, cylinder is too large at an XL.
Shunga: Here is the cylinder I got. I REALLY recommend it. Cylinders that are straight (girth is the same up the whole tube) are very ineffective compared to the ones that taper up the cylinder (smaller where the head of the penis would be) I also can use LOWER pressure (only 3 HG!) and it really pulls, and EQ stays great.
