My wife calling me a good boy is part of our bedroom kink, but I'm getting tired of it.

I (m28) was calling my wife (f27) a good girl as part of our kink, but I'm starting to feel like part of our kink involves her treating me like I'm her child. I'm getting very tired of this, and I'm not sure why she's doing it.<br><br>**TL;DR** After we married, I started calling my wife a good girl. She liked it, but after a while, she started calling me "good boy," which I find humiliating. I think it's an attempt to control me. I plan to end our relationship if it continues. I feel a bit dumb for getting sucked into this, and I'm not sure what to do next.
