Just did my first 7.5hg pump for 45 minutes & I can totally see how addicting this can be.
When I pumped in the past I would start from a low pressure for 10min (like 5hg), then move to a high pressure(about 10hg) for 10min so I could watch a few vids while mentally preparing to goon hard. But I've now found that longer, even if at lower pressures is more effective.
I did a 5hg pump for an hour 4 days ago & that was the plumpest my frenulum has ever been, though my foreskin was constricting, so I knew that next time I would have to put my foreskin further up to prevent that.
So today I made sure to do so, I put on some good PMVs & got to work.
I have a kind of mediocre pump from a sex toy store, very much oversized & keeps sucking my balls in which is annoying since I have to grab a paper towel to pull them down. I went up to 5hg in about 2 minutes & started a timer, then went up 7.5hg after a few minutes. After about 20 minutes one of my balls started hurting & I had to drop the pressure to 5hg to pull it. But that wasn't enough because 8 minutes later it was really about to have a catastrophic suck in, so I had to drop all pressure to make adjustments.
When I felt my penis it felt plumper & bigger than anytime I had pushed to 11hg for a few minutes, but I was compelled to keep going. I was really frustrated with adjusting my balls so I quickly pumped back up to 7.5hg & I barely felt the pressure, my penis was so numb. But I felt it in my balls, for the lotion I had used to prevent my foreskin from getting pulled down by the rubber seal had spread to my balls, so I had to hold them down with my left hand for a while, but the strain was too much & I had to cut it at 45 minutes.
When I pulled my penis out, my frenulum was still overly plump (guess I need to do some more foreskin stretching) & my penis was very plump, with some more swelling around the shaft. When I gripped it I felt ecstatic, IT FILLED MY HAND, it was only somewhat more, but my fingers didn't touch my thumb like usual. I always imagined what it would be like to grip the thick cock of another man & here it was on my very own crotch. I then jorked it for about 15 minutes before cumming, certainly a missed gooning opportunity, but I really squirted a lot since I had been holding it for a few days & I've been getting back into working out.
I see why so many of you love doing this, just feeling the size & how disproportionate it is just gives me the horniest shivers! Might invest in a pump that can actually hold my balls, or I get into scrotum stretching.
Edit: forgot to mention I got petechiae all over my penis
