Low-vacuum pumping?

In the past when I’ve tried pumping, I used a vacuum level of about 4.5-5.0 inHg, but fairly quickly got discoloration and little red dots. Recently I’ve tried 3.0-3.5 inHg, and it appears that doesn’t produce those problems, at least so far. And my dick appears to be very nearly as big while pumping at that level as it is a higher levels. In fact, I picked that level as the lowest one that seemed to give me full “expansion”, or very nearly so.

But of course the question is whether that’s doing any good. I’m looking for two things from pumping - first is the increased responsiveness and EQ that Avocet has talked about, and a distant second is girth (but I don’t really expect that to happen). I am absolutely NOT looking for the lymph edema that lets you pack the tube.

There’s also the question of how long a session I can/should do at 3.0-3.5. I started at 10 minutes, and am now up to 15, with no apparent problems.

Is this low-vacuum pumping worth doing at all? Anybody out there with long-term experience at those levels?

Low vacuum pumping is recommended by a lot of us vets. Gprent has a whole thread about it; you should read it here in the Pumpers’ Forum.

Low vacuum does a lot of good; and without the nasty side effects of high vacuum pressure. If you gradually increase your time in the tube up to 15 min., you won’t shock your cock. :)

where exactly is the link to Gprent’s thread?

I think this is the thread avocet8 is referring to?

I believe this thread is the one: Do you guys regret spending all that time on pumping and why?

thanks!
