First chastity cage

I remember, back in time, when my exgirlfriend and later mistress have decided, that we have to lock my cock into chastity cage, she let me decide which one I am gonna buy. When I send her which one I chose, she replied me - it is gonna be too big for you. I have not an idea that a chastity cage can be too big! I thought that all of them are for tiny dicks!
