Urethra sounding for girth gains?

I was just wondering if anyone has any experience with this. Would increasing urethra size with sounding expand the penis from the inside out?

Any thoughts welcome!

I used to do sounding, but did for experiencing the very unique feeling of it. Never had any thoughts of gaining girth from the inside out. I have seen guys sounding with some very large sounding rods (and other devices) but never noticed any unusual girth resulting from it.

Remember, the sound is only going down the urethra and gaining girth really comes from expanding all three of the main penis chambers.

I have also done some sounding primarily to improve ED with a vibrating sound. I don’t see how it would have any effect on girth.
