lord of the cock rings

hi all this my first post.my question is about cock rings and where to buy quality im using a doc johnson at the moment and its working well,i like the feel and width of the ring.im using this for ED and just when i thought all hope was lost i bought a ring on a impulse and bingo.ive tried oxballs but they seem to stretch too much im needing something with bite can anybody recommend a online store.would appreciate some help

I have suffered from ED (diabetic) and have used many cock rings over the last 15 years. The best tight fitting cock ring I have experienced is the high tension medium size Osbon band from Erecaid. It costs about $25 with shipping but it is top quality. I have been using it three or four times a week for over two months and it is still going strong. My Base girth is about 5.1 inches so if you are over 5.25 inches, I would recommend the large. It fits very tightly so it needs to be removed every twenty minutes.

What are cock rings used for exactly?

for after p eing girth wise to retain the expansion for long periods of time leading to adaptation meaning permenant growth or for when you get a hard on to strap on and make you dick even harder and more massive
