experimenting with testicles pumping.

[Ballooon111]

I'm experimenting, trying to minimize the bloating and maximize the testicle size by using smaller jars and restrictive o-rings.

Pumping testicles only worked well for me. Then penis or both afterwards gave great results. I never tried rings
I got to crazy pulsed high pressures with testicles only.
Fantastic results. Narrow tubes were best as I have a narrow pelvis
Your mileage may vary

The testicles themselves are usually first to fill when pumping, so shorter frequent pumps may help to get the result you are after, without having to resort to o-rings, which are sometimes uncomfortable.

Thank you for the info TinyMe, I'll give it try.
