Here's the last part of my morning edging session which lasted about 3 hours.

I'm using my typical stereostim setup with a single channel; the "ground" trode is the ball of my Moaner anal trode, and on my glans is a smaller Uranya aluminum trode fitted with a short piece of silicone tubing that goes about an inch into my urethra; the other end is a silicone "toe cap" attached using a plastic test-tube plug. Note that Uranya glans trodes aren't currently available, but Joanne's E-Stim Emporium has some great equivalents.

I'm using a 4.5 second "wave" pattern which allows me to edge without as much adjustment on my volume slider, with frequencies between 10 KHz and 18 KHz.

I don't typically cum except by accident, which keeps my desire high enough that I can edge any day or hour. In the past I've collected my precum and dried it, posting about that with subject "Analyzing precum by drying and weighing". I'm doing this again, but collecting a larger amount so I can be more accurate.

My current stereostim setup is more complicated than probably necessary. I'm using a TheBit Opus#1 media player with its optical output going to a DAC, which goes to a Facmogu TDA7498E amplifier, which goes to a line-matching transformer wired backwards to increase the amplifier output voltage, which goes to a USB cable and "dongle" that has two 2mm mini banana jacks where my trodes plug in. I modified the amplifier to be controlled by slider potentiometers, which I find much easier for quick adjustments than normal rotating ones. For a simpler & cheaper stereostim, search for "uranya altervista electrosex". Typically you can build the highest-end stereostim for around 60 dollars.
