NO…. I have had a couple of cystoscopies. No way in hell I’m shoving something up my c*ck! To each his own, just not for me.
Silicone is much too rough for me. Stainless steel is lot more comfortable. Sounding feels great, but it affects every time some nasty burning pee anyway, so I don't do it very often.
Those of you who have had a medical person catheterize you do not understand the sexual pleasure you get from doing it the right way. If you do it yourself with the correct diameter sound it feels amazing. Stainless steel sounds designed especially for insertion into the urethra are a must for beginners. Silicone for the experienced sounder. Lubrication is a must also. So is cleanliness. The sound and lube use must be sterile, the correct size sound, and plenty of lube used as the sound travels into the urethra. Pushing it along only causes problems. Let gravity do the work. What you do is lay back, lube up the end of the sound, and start it at the end of your cock. Slowly ease the sound in the end adding lube as you go. At some point gravity takes over and the sound slides on in by itself. That is a great feeling. Using too small a sound the feeling is less. Too large and there is pain from the force and stretching. Get it right, such as a 7 or 8mm rod at first, and the sound will slowly ease into the urethra providing great pleasure. The cock should respond becoming hard as a rock. Then you can softly slowly stroke yourself and enjoy the sensations. With luck you may be able to get the sound to stimulate your prostrate. That feels real good when you do.
