Purple blotches on glans when pumping

I have recently started pumping and I notice that after a couple of minutes in the cylinder, purple blotches stat appearing on my glans, I believe blood is pooling under the skin. This happens at 5in hg. I do not exceed this level of vacuum and even though after massaging the glans it goes away, I am a little worried. Does this happen to you? Should I be worried, or will this go away after my penis gets adjusted to the vacuum?

Pumping is a function of both time and pressure, so the amount of time at 5”hg is also contributing to the blotches. How much time are you spending at that pressure?

The best way to proceed is reduce the pressure to under 4”hg and depending on the time factor, perhaps reduce that also. Depends on what your answer is.

Gprent, thank you for answering. Since I am just starting out, I am very cautious. I don’t spend more than 5 minutes in the tube. The purple blotches start about a minute in and by 5 minutes, 75% of my glans has them and is almost uniformly purple.

OK then, the next time you pump stay at the 3.5”hg level for 5 minutes and see what happens. If that reduces the problem, keep using that pressure and as you gain experience, start adding more time in 5 minute increments. There is no need to go above 4”hg to get good results and the level I stay at is in the 3 to 3.5”hg range.

That was my solution as well. I was more interested in whether others also get this and whether it is something to be worried about. Thanks for the input. If anyone else has any wisdom to add, please do.

Also, is it ok to stretch and jelq after pumping? I find that I tend to get hard when stretching, but after a few minutes in the pump, I can stay flaccid or flaccid enough to stretch and jelq at low erection level. I am going for length more than girth for the time being. I would like to reach 7in BPEL before concentrating on girth.

I do my jelqing before pumping to prime the penis for pumping get the blood flowing and then set into the pump at 3.5hg for 10 minutes then I up the pressure to 5hg max for another 5-10 minutes. In the end my pumping set is 15-20 minutes total. I think if you are pumping straight to 5hg from the get go then that is what is causing the purple spots. I pumped for several weeks before even attempting 5hg it was only 3hg for me back then 10 minute sets. Just take your time with pressure increases instead increase time slightly before increasing pressure and 5hg should really be the max for anyone.

I tried again yesterday at 3.5in hg, and the effect was lessened, so the pressure is probably the problem. I will take it easy for the next couple of weeks and stick to around 3 in hg.

I am currently doing 2 5 minute sets, one before and one after my manual exercises. How fast should I increase the time? I definitely see more expansion the longer I stay in the tube.

You may also consider that your gauge is not very accurate, and has misled you.

It is a brand new mityvac, but I suppose it is possible.

I don’t get any lymph fluid buildup.

Do you add warm up before you pump?

Yes, I’m either in the shower before or I soak in a jar of warm water for 5 minutes.
