Any seasoned advice appreciated?

I used AnotherOldMans advice, I use the Encore pump but was having trouble finding the right ring
that would keep the erection. He suggested using 2 rings, which I did and also using a penis sleeve.
The penis sleeve helps with the "snapping" of the rings when you slide them on the penis, also not
as much pressure or pain from keeping the rings on for 20mins or so.

Thanks guys, for all the help and expertise, the best kind of knowledge is learned from the experienced

I ended up purchasing a Soma Manual and I also got a Pos T Vac Bos 2000, battery powered, I'm going to be asking a ton of questions in the next month or 2, mostly related to techniques, fine details and probably alot of questions about the constriction rings, I have a feeling I'm going to go through a ton of trial and error with finding suitable one for me, and also these cock sleeves that you guys mention alot, I've already discovered firsthand exactly what hinging is, thanks for the help
