Sounds come in a variety of styles, and are used in slightly different ways. These are Dittel sounds which have a round end and a flat end (which unscrews in this set.) They have no curve and also feature two grooves at the round end.
If it's your first time selecting a size, you should select a sound that is the largest size that can be fit into the urethra without any stretching feeling. Keep in mind that the urinary tract inside of a penis, is often wider than the urethra itself. While those equipped with vulvas sound as well, it's important to keep in mind that the urinary tract is much shorter.
We recommend using sterile surgical lubricant (such as Surgilube) or antibiotic ointment (like Neosporin) as lubricant with all sounds. And of course, it is important to clean and rinse the sounds well after each use. For more reading on urethral sounding, Winter Tashlin wrote a very informative piece and it's a great read.
