U guys have great sacks new an wanna try this pls help

[Givemehead]

Will a cock tube give any result or does it have to be like a jar or bowl to get sack to swell

[Indeed]

I have a 1.75" cock tube and a 2'' cock tube and they didn't do much for my balls. The scrotum stretches out pretty well inside the tube, but there wasn't much expansion.

Definitely try a jar, or a wider tube. You want something that gives your balls and scrotum enough room to expand outwards instead of being stretched.
