Hi there!
Yes, we use good quality silicon lube, it’s so important. Hubby has the CB-6000, plastic and metal now, and you need to lube around the ring and the part your cock is in particularly. Don’t use water based lube as it sticks horribly after it dries. Hopefully that’ll help a lot. And beyond that then it’s making sure you get the ring size right, try different ones, and then build up, a few hours, to a day, to longer…
