I am using the SomaCorrect's A cylinder with both of the inserts. I suspect it is because of my very small girth, but as far as i know there is no smaller inserts than the two black ones that come with the device available.
Hi, you could try pushing the cylinder & pump unit back into your body fat before you start pumping.
I can't remember the brand of my VED, but it came with a flat rubber donut piece that you put on that keeps the VED from pulling up extra skin or scrotum. See pic. You put the rubber "donut" on by sliding it over your shaft only, so that it protects the scrotum and extra skin - it actually works for me.
You can also put a "silicone sleeve" around your balls preventing them from traveling up. Of course observe circulation.
Also putting a piece of cloth or similar below your balls when sitting down can help.
Restraining the scrotum from moving up so to speak.
I have this exact problem with VED.
bentbigd, if you can figure out what brand VED you have that would be nice. That exact flat rubber donut piece you have seems like it works great, and would be a solution to my problem.
