Is this doing something?

So I am sitting there pumping I have gotten accustomed to it. I noticed I am not feeling a tugging sensation. Instead I am just inflating my balls and cock up. It gets thicker but I have a spongy fat feeling.

It’s fluid build up and…is this beneficial? It goes away. I am just curious to know of it’s hindering gains.

Wish I could assist you with a knowledge nugget but I’m fairly inexperienced with pumps, let alone ones that cover the balls as well. Personally the sensation I get is an uncomfortable pull only on one section of my penis, right by the base, but generally, in medicine a spongy feeling is tied to fluids since I doubt you’re getting an infection from pumping. Unless you don’t clean it, in which case you might want to clean it.
