Female led relationships discussion

I’ve requested my kh to marry me and I’m hoping to begin organizing the smaller details now. I was curious if anyone here in a D/s FLR setup has included their own unique vows, and whether you chose to keep them private or share them openly. Just so we know: I view the legal marriage part as something straightforward, like going before a justice of the peace or doing it in Vegas. We could handle our personal vows separately afterward in private. I have several ideas swirling around but would really appreciate hearing from those with relevant experience. To me, this matters greatly. Our relationship has always been about evolution, yet one steady element remains: my commitment to her as my kh/dominant/disciplinarian, and hers to me as her caged/sub. I’d like us to pledge ourselves to this dynamic for life, and I believe that would make it truly special.
