Kali's Teeth Chastity Cage

A very recent purchase which I had been thinking about for sometime and arrived today. Along with a couple of others, this is the first tried after packaged opened. I had envisioned a painful bite but at present I hardly notice that it is on. While I am fairly flaccid presently, it has shown no tendency to slide off or move from its applied position, which it cannot due to some Bling I have behind the Glans Penis. Should I get excited and enlarge, I do not believe the points will cause any problems.
The only concern that I have with the whole package is the quality of the lock. While it does work it feels gritty and does not function well. I would hate to be locked and unable to open it. I will replace it with a better quality lock as soon as.
