Does anyone else do chastity without using a cage?

My wife has been controlling my orgasms for about six years now. We have used cages in the past, but she still likes to use me from time to time and gets annoyed at my lack of performance after being locked up for a while. She demands I use the honor system. We have known each other for thirty years so she knows when I cum. She hates how I act afterwards, as do I, so hence the lifestyle. I guess I want to know if anyone else does it this way, and does anyone consider it kind of a cheat. BTW, I get one a year, maybe two.
