Clank, I’d like to give this a shot. I’ve been pumping for 1.5 months so I’ll try to help. Do you have a gauge on your pump? How much Hg are you using and how much time are you going for?
To answer the question. It’s not unusual to get red spots on the shaft after a session. I still get them now and I use rather low pressure (3.5- 4.5” hg).
If you haven’t taken days off it would probably be a good idea to. Give your penis time to adapt to pumping, usually round 1- 2 months.
Also, you might want to jelk for 5- 10 min before pumping and between pump sets to help restore circulation in the penis. Heat also helps with loosening things up, tissue, ligs etc.
Try to keep the pressure low for now and set times to 5- 10 mins each. You can increase these later after you have adapted better.
Hope this helps
