Pumping Cylinder Sizing

Hey all. I know this isn’t the correct forum, less active member here. I have a question about choosing the correct cylinder size. I’ve seen the primary thread (Selecting Your Cylinder Size) on correct sizing, but I was wondering thoughts on a few things.

Currently at 7¼ BPEL and about 4.8 EG at the shaft base. I have a 1.75" cylinder that I’ve used for air pumping occasionally before intercourse. Now, I’ve got a slight upward curve halfway down the shaft, and even with lube I feel like I drag on the wall before hitting my potential. My head plus the drag seems to only go so far.

Should I be upgrading to a 2" cylinder? I feel like this would grant too much room though. Or should I just add "way too much" lube? Any suggestions to get maxed out in the cylinder?

My goal is girth currently, and I have a bathmate that I use during my daily shower (mostly for strengthening, lower pressure pumping) but that is occupied with water for the "extra space". But I like using the air pump to get that little extra thickness for the lady.

Appreciate the positive input.

The only down side of a larger tube is that you may get a ball sucked in, but that is manageable. From a PE point of view there is no difference in a 1.75 or even a 4” cylinder: the vacuum applied to the penis is the same. Obviously packing the tube is more difficult with a larger size.

Before purchasing another cylinder I would try extra lube especially on the glans and other contact points to make sure they can slide up the cylinder. If you still have drag problems try milking the tube a little to move the penis around. Sometimes releasing a little vacuum then milking then pump back to your target vacuum level can be enough to free up the penis.
