A couple of days ago I posted "Frustrated" because of my own inability to stop trying to top from the bottom more than anything. Now ... Because of hygiene issues and her general lack of interest in doing anything with the chastity device, we ordered a second tube so we could switch them out every four - five days (the intention is that I will switch them under her supervision). The new tube is a CB6000s - the smaller version of the CB6000 which I currently own. We switched them out last night and I was shocked at the difference. With the CB6000s tube, I'm finding it much more frustrating as there is absolutely zero room to grow or get even partially erect. It's even more emasculating than the CB6000 because of this. When my wife and I discussed these findings at lunch, she said "good, maybe that will help you stay in line better."
