I got one and recently did a webtease series, locking me up in between. I have to agree with everything what SC said so far about the review, just one problem:
The tube doesn't start after the 'cockring', probably what makes this cb special, it goes all the way to the root of the cock. But then the balls get pulled forward, and the skin at the underside of my cock, where it connects with the balls, gets 'pulled in two directions'.
What i mean is the tube pushes it back, while the balls get pushed forward and at the small point i got some blisters, it got quite painful, and well my cock is 'free' now and healing up.
Anyone else had that experience? How do you put the device on?
