Has anyone used Urethral Sounds to expand the urinary tract opening? I have a small piss slit, often with irregular flow pattern urinary stream. I'm wondering if anyone else has tried, and succeeded to enlarge their slit and urethral opening. From what I've read so far, they work well in the medical field for doing just that. Obviously they have to be sterilized and 100% clean before inserting into the urethra, but any other experience or thoughts are welcome too.
