Urethral sound / probe

I'm new to e-stim (and zity.biz), but am already enjoying putting my creativity to work designing DIY probes and systems. Today, while at a garage sale, I noticed a small meat thermometer. As I got to thinking about its design, I realized that it's the perfect shape for a urethral probe: very thin, tapered end without being too pointy, just about the right length, and very smooth. I also realized that, since the needle on the thermometer is attached to a coil inside, that it was hollow, and could be easily connected to an inserted wire. After buying it (for 25¢), I took it home and used a Dremel with a cut-off wheel to remove the dial from the top, leaving a shoulder for easier handling. Not only is the space inside big enough for a wire, it's big enough for an _insulated_ wire, which means that it has potential as a bi-polar probe! I found that the plastic tube from a can of spray lubricant was just small enough to go inside. I have some stainless steel binding wire (from Harbour Freight) that just fits inside the plastic tube. Since the wire is strong enough to hold the whole thing together, I'm going to cut the outer tube in half, solder the stainless wire into the end piece, then slide the plastic tube over it (and into the end piece). Next comes a very tiny O-ring to insulate the two halves of the outer tube, then the top piece put on after I solder on a connecting tab to clip to. At the end I'll put a fiber bushing, so that I can solder a washer to the stainless wire without it touching the outer tube. I know this sound complicated, but anyone with an imagination can probably come up with more fun ways to use a meat thermometer!

How about using Heat shrink on the Tube!.. It seals and shrinks very tight..

Having a probe in my cock and one in my ass and have the device send various shock waves of various degrees to me is absolutely fantastic.

I love to include it when I do self-bondage.

SO HOT !

I'm wondering if there are any simple e-stim devices i can make, and whether something like a D-cell household battery has enough power to be useful. i've never tried a TENS unit, but really hope to meet someone who has one, and can allow me to try it.

I get horny doing many things and consider myself quite a pervert, but urethral probes are a bridge too far for me....

I too have used different items as sounding devices. How about a picture?

I've used a portion of bicycle cable housing to e-stim deep in.

Using a bicycle cable is a REALLY BAD idea. It has sharp edges and is totally dirty--even new out of the box.

Be a sport.

BUY a bipolar urethral electrode. What you are describing sounds like it will work, but it needs to be very well finished and smooth as well as able to be disinfected.

It's your dick. Treat it well.

Susie, his post is 2 and a half years old! It's two years since he last logged in. I hope he's still alive!

I was half hoping for someone to post on the fish tank tubing, lol. What will they get up to next I wonder?
