Flaccid pumping

Hello,

I have been pumping for 2 weeks using a 2.25 inch internal diameter mustang pump with a silicone sleeve and a pressure gauge. I currently pump at 2x15 Hg with a 5 minute break between sets and heating before and after.
I switched to pumping from using the vac extender 3 because of the time required; the vac extender requires several hours to be effective versus under an hour for pumping. I clamp as opposed to doing girth focused manual PE exercises for the same reason, currently using 1 medium cable clamp at 5x15 sets at the base, with heating before, throughout and after with 5 minute breaks between 15 minute sets.

For me I do not feel the pumping sensation (very little if at all) and although pumping is done whilst erect, what would be the effects of semi flaccid pumping? I know that the pumping vacuum ‘pulls’ the base of the penis out so perhaps this would act as a low force extender

You would have to pump at very low pressure. When I pump, I’m always at maximum erection by the end of the session.
