Water pumping with traditional cylinder outside the bathroom. How do you do it?

A tiny bit of Sodium EDTA would remove the hard water feeling. But it will significantly increase the permeability of the skin and EDTA can have contamination so you’d want to be careful with the supplier you get or do some purity testing. I’m not sure if you can do a melting point test on EDTA and checking the purity with a spectrophotometry will destroy the sample if there is the tiniest trace of iron, probably other metals, in the solution. I’m not sure if you can recrystalize EDTA for higher purity.

I believe what people are utilizing here is Epsom salt. This is commonly used to sooth tired tissues (I.e. Soak your feet after a long day). The concept is similar except within the tube of your pump.

So while performing a warm-watered pump session you add some Epsom salt and soak your penis at the same time. Not only does it feel good (in my opinion) it also does increase your skin’s permeability - resulting in a pleasant plumper/thicker afterward.

Make sure to cycle water through your pump and tube afterward so as to avoid residual build up or unwanted degradation to your equipment.

Hello!
A couple of questions.

If you pump with water.. Do you still use lubrication?

If you pump with water.. Do you have to use the same pressure of when you air pump?
