Thought I would post a few pics of the flex wand setup I own. As the pics show, the bits thread together to give me quite a few different combinations. The large ring is frenum ring that sits just under the glans hugging the cock. The red part is a urethral estim probe (only the tip is conductive). If you have not discovered estim, you really are missing out on one of modern technologies latest gifts. The other parts are pretty self explanatory. FYI, the diameter of the parts is 3/8" and at the greatest extension, 8" long. The estim probe is a full 10". I am currently having a new upper section made that will have a low profile (flattened) PA crossbar and the more typical ball on the end. The new section will still allow me to connect all the other pieces to it with the exception of the estim probe which requires the existing upper section. The new upper section, while hollow, will not have adequate bore to pass the probe. The main reason for the new upper section is the current one has its drawbacks during intercourse (mainly the extruding crossbar post) and I wanted a more typical PA wand appearance for times when others might see my jewelry. If anyone is interested in details, please PM me.
For those of us that enjoy urethra play, the fear of a urinary tract infection is always in the back of our mind. I started off doing the extended boiling as I lacked an autoclave, but that was a real pain. I then remembered that as a kid going to the doctor that they always kept the oral thermometers in a container filled with cotton soaked in what I later in life discovered was denatured alcohol (ie 100% pure ethanol that has been rendered undrinkable...I remembered the thermometer having an awful, bitter taste). A bit of research confirmed that denatured alcohol was an excellent disinfectant due to being a very strong desiccant. I use an ultrasonic cleaner along with the denatured alcohol to thoroughly clean all the parts of my flex wand system and then I store the bits in a bath of denatured alcohol. When I get ready to use them, I rinse them off in water to remove the denatured alcohol as it would not be a pleasant feeling inside the urethra.
I have been using this technique for about 6 months and have had no uti issues, so it must be working.
