I have the keys for the moment because I need to unlock the belt regularly for my body to rest. The belt makes the skin chaffing after many hours, so my girlfriend and I agreed that first I keep the key to unlock when needed without disturbing her with these issues, then, when I will be used to it, beeing able to wear it a few days without unlocking, she will get the keys. This begining is quite a challenge. As it is very comfortable in the first hours, it becomes evil over the hours, especially with the impossibility to get an erection which is very frustrating. Sometimes I have doubt about this lifestyle, I hate my belt. But the manufacturer says that the lock up periods needs to be increased step by step, listening to the body reactions, then the belt should become very comfortable. I hope he's right!
