Hegar Urethral Sounds Kit
Product Review (submitted on February 29, 2012):
I highly reccommend this product for anyone interested in doing insertable fun. Especially if you plan to buy various kinds of plugs. Not only does the Hegar sound kit make it easier to figure out what will fit inside your dick, it's tons of fun doing it. Also if you are interesting in stretching your urethra to accommodate bigger toys you really need to get one of these kits. I haven't tried any other sound kit but I am extremely happy with the Hegar kit.
