Actually I'm very happy with the Dolphin Vibe cock ring or my girlfriend. But the diameter of the inner ring, in other words for the penis, was for me too small even if stretchy is in the product description that attach through the small opening more of a torment. I therefore have the inner ring cut out simple and then use the ring, the matrimonial for the testicles would be as Cook ring, which also works fine. Nevertheless, I advise with larger penis diameter of purchase!
