I tried to destroy them by running boiling water through the needles for about 5 minutes. First the pain hits you as you start pressing the water through the needle, and I needed to slow down, but after a few seconds it was okay to have the water flow, and strange but true, the feeling became sensational.

There may be a lot of damage, but unfortunately they are still working.

This sounds like some fun, maybe I should talk my wife into doing some of this as well. She's really handy when it comes to using needles (being a phlobotemist and piercer).

My wife has been pushing needles through my testicles for years. Her favorite is ice water. Wow!
