I have a question about what I am experiencing. I am wearing what I have found out is a Chinese knock-off of the real CB-6000. Good prices tend to be to good to be true, so I have found out. Anyways my problem is that I am experiencing some intense burning and pinching behind the scrotum from the ring. I have read here on the forums that the Chinese knock off CB's come with rings that have a groove in them, this groove can catch the skin and pinch, chaff etc. My ring has the grooves in it, the real CB rings do not. This sounds like what I am dealing with. What I am feeling is rather intense at times, it is difficult to sit, drive and sleep. A few times I have thought about asking for release until we can figure this out. I currently am becoming concerned about my health with my scrotum skin. I am only on my 3rd day of forced chastity. I have been lubricating with silicone lube several times a day, it helps but it is not the answer. Has anyone else had an this issue like this from the Chinese CB-6000s? I heave read that some men use surgical tubing around the ring, I think others have used some type of gasket material in the groove. On a side note: I have ordered the 2 larger rings for the CB-6000. Currently I'm using the largest 2" ring and the pressure is almost to much to bear. I have more excess skin around my cock & balls than most men, so I'm hoping the larger rings will provide the extra room I desire yet still keep me locked up tight with no chance of the balls getting through. I should add these new larger rings are from the CB manufacturer, so these will be the solid rings, they will have no groove. Hopefully this helps eliminate the burning, pinching & chaffing. Thank you for any info!
