The Sounds

There is a curve in the male plumbing system; the J-curve on which the Van Buren sound is designed to accommodate that curve, allowing the sound to slip down the penis and into the bladder easily. The problem is that if the bottom gets hard during the process of insertion one has to wait until the erection subsides, as the curved sound cannot be inserted (or removed!) if the penis is hard. It is possible to negotiate the curve with the straight Dittle sound or Sim sound by changing the angle of the penis during insertion, but this requires a bit more skill and sensitivity on the part of the top.

The diameter of sounds, catheters and some other medical instruments is expressed in the French system. One French unit (Fr) is .33 millimeters (.3mm for ease of discussion). Thus, an instrument which is 20Fr is 20 x .3 = 6mm in diameter (0.24").

A word of caution: This kind of play is not something you should engage in with someone who is inexperienced or who does not understand all the necessary precautions. Carelessness can result in infection, injury, or other traumatic problems. You should be introduced to this kind of play in the right setting by an experienced, careful person who cares enough about you to exercise all the cautions set forth herein.

 The following procedure for sterilizing the sounds is based on the fact that the sounds are used by only one person*. The sounds need to be cleaned properly before and after use to prevent bladder infections. Before actual insertion, using a tissue, scrub each of the sounds with alcohol to kill any bacteria or fungi from the air or inadvertent touching.
