I have a cb2000 and couldn't ever wear it for more than a couple of hours because it felt like my nuts were ripping off. My wife and I were getting pretty discouraged that long term wearing would never happen. Then I saw the birdlocked and thought that was the answer. I've worn it for a few hours at first to get used to it and it was VERY comfortable. Our expectations were on the rise. So last nite I put it on and gave her the key because she decided that I needed to be forced to get through the nite with it on. I took a double shot of Nyquil to help sleep and off to bed I went. For the first 3 hours I was up every 15-20 mins. then for the next 3 hours i went about an hour between wake ups. What was waking me up was a white hot pain in my sack. I had to keep trying to pull my sack so that there was some slack there and the jewels perhaps wouldn't come shooting out. When her alarm went off I yelled out my safeword and got unlocked. My question is, is this what everyone goes through? If so, how long does it take to get accustomed to that kind of pain? If it's not normal, what do you think could be the problem?
