Flaccid pumping?

Maybe you more experienced guys can go that long, but I know for me after 25 minutes in the BM my head is smooshed against the side and my whole penis is a rich purple color (normally just as white as the rest of me). I always Jelq a little bit right after to get the blood pumping again though.. An hour and I might actually explode!

I might explode to if I go that long to with full pressure, that it’s the trick with BM to learn our sweet pressure spot.
But if I stay a half inch under my EL under the entire session, focusing to stay at max, moderate pleasurable pressure.. I come out with minimal fluid build up and just a redish look..
And I jelq 5-10 minutes after session too to get out more of the ppumping session.

I suffer from mild ED and often start out flaccid, but have discovered that by combining low vac pumping with a wand massager held on the tube for just a few seconds every minute or so, I can quickly bring about an erection on demand while under vacuum. From then out I continue applying the massager whenever I feel the erection starting to subside.

I will say it is intense and takes self-control to keep from starting an orgasm, but with care I can keep edging with a hard on like this for a long time. I seem to pack the tube must faster and if I do this in the evening every couple of days, I’m also aware of having awesome erections all night long and better spontaneous erections when aroused.
