Well, no one got it. SuzukiGS came pretty close.
It is used for theraputic treatment. It's a tool for your tool, if you have phimosis that is. It is inserted into the narrowed foreskin (uncircumsized guys know) of the tip of the ***** and is used to spread it manually to stretch the tissue. Some versions of it have click stops to hold constant pressure on the tissue.
Yes, I'm through using it. LOL! Someone is gonna ask! Actually a urologist gave it to me. He got it in Japan at a medical convention.
