Female led relationships discussion

Hi I’m new to this site, I am an early 30’s Male in a steady relationship with my Key holder. We have experimented with shorter periods of denial, but on New years eve 2014 I bought a chastity belt and gave her ultimate control over my orgasms for as long as she sees fit, since then I have been allowed to cum 11 times. However the last time I came was without permission, she pinned me down and fucked me hard, all the while forbidding me to cum, I couldn’t hold it and came despite express instructions not to, She was very angry with me said I need punishing. After thinking about it for a week she has decided that I need to be humiliated as well as punished, so she has commanded me to join this forum and let complete strangers decide my punishment. Please post punishment suggestions for me, and my key holder will then pick one of your suggestions and enforce it. Please be kind
