Female led relationships discussion

Hello everyone, I could use some advice. George used to wear a CB3000, but he stopped because his foreskin started swelling up. We tried all sorts of solutions without much luck; the swelling would appear after just about 20 hours in the device. Consequently, we bought him a CB6000 instead. Now, though, George is hesitant to put it on again for fear of that same swelling returning. I certainly want him to give it another shot at least. Any ideas or tips from you all?????? Thank you very much, George’s KH
