Instead of ace/condom, should I just get a tube that barely fits?

For my first pump cylinder, I was able to max out only near my base, but not the upper 80%. I tended to get a lot of the lymph fluid donut, especial at the circ scar.

So then my next cylinder was a 1/4" less in diameter, and I maxed out the bottom half pretty quickly, and the the upper half after about 20mins. But still I was getting the donut and just outter lymph enlargement.

I went down the rabbit hole of reading how the outter skin is less tough than the inner tunica (and its the tunica we’re really trying to grow) and the solution seems to be to use a condom or wrap an ace bandage to keep things tightened in.

But after trying it, it’s very "clunky"

Should I just get another cylinder another 1/4" smaller … which my erect penis will barely fit in… and pump with that to prevent the outer skin donut, and better tunica expansion?

Staying with the smallest cylinder you can fit in will help reduce the donut effect.

How long are you staying in the cylinder, and how much vacuum?

I’ll usually do 10-15min each set, then take about 3-5 mins break doing firegoat rolls. Usually I’ll do 2-3 sets for a total of 30-45 mins.

I’ll definitely be maxing the tube at around 45mins, but that where I get the most donut effect.

I guess it’s better to just have the smallest tube to maximize girth growth of the tunica and not the outter skin?
