Accustom your urethra to insertion with these double ended urethral sounds.
Hegar Urethral Sounds are the ideal tool for expanding your urethra in a slow and gentle way. Each sound gives you two sizes so you can gradually work your way up to the second. The first starts off at 5 millimeters wide, and expands to 6 millimeters on the more advanced end. The second starts at 6 mm and so on. You can work your way all the way up to the 10 mm Large size if you wish, or you can just get to the point where you can wear your favorite penis jewelry comfortably. Of course you could just get one to experience the sensation of cumming while your cock is stuffed with metal.
