RBM: I headed your warning and used the fridge instead. The thought of frost bite didn’t seem pleasing.
Big G” I used your method with talcum powder.
I am very pleased with the results. Attached the weights after hanging and was able to keep on by using a very large o-ring that firmly slipped over the glans but did not choke the old fella. The cool down was slow and relaxing to the unit. I believe that I will be adding another step to the session.
What I am thinking of is getting another set of rings and letting them sit in a heating pad and using the heated rings first then attaching the cold rings for a last step.
Any thought about this out there?
