Mistress locked me in a cb3000 on December 16. It's still on (although it has been removed for very brief periods 3 or 4 times). I went from December 31 until February 2 without removing it, and only removed it then because the numbered plastic lock broke, and Mistress gave me permission to remove the device to check for problems, (there was a big one) and to allow for changing the ring, as I will tell about below. I started out using silicone lube, which works well, but I found that it doesn't last long, so I thought I'd try "baby oil gel", as suggested on the cb website. What a difference!
It lasts a long time, and will wash out of clothes, unlike silicone lubes. Lubing the ring and any point the skin contacts the device is important.
I am not shaved (almost impossible when you can't remove the device), and find that the hair acts as an additional lube.
As for driving, I was having the same problem, so I changed 2 things. One was the lube, the other was my pants
. I went to cargo pants or carpenter jeans, both of which are "loose fit", and so don't bind, push or squeeze like my regular jeans. I've done a couple 5 to 6 hour non-stop trips with no problems. Also, no underwear or very loose underwear helps, things need room to move down there. That "burning" sensation is from skin getting caught or "folded" in the ring contact areas. More room helps eliminate that. Also, keep things warm down there, so the skin stays looser. I have a real problem if I spend too much time in the cold!
Recently I changed 2 things about the cb3000 also. The first was I removed the "Points of Intrigue" after I found that they had literally made holes in my shaft! Yes, there were actually holes, bloody wounds.
At the same time, I changed to a solid ring, rather than the hinged one that comes with the cb3000. The hinged one is great if you are not going to be in long term chastity, but the hinge point can get irritating after a while. Much more comfortable now.
Hope this helps. Good luck.!
There's a fine line between cuddling and holding someone down so they can't get away.
