What do you think about male chastity?

I have always been into the idea of someone having control of my sexual desires. I have no idea how to propose this to my girlfriend. I have had a chastity device, I have worn it and it’s perfectly comfy. Do I ware it until she makes a move on me, then tell her hey here are the keys. What would you think? What would you do?
