A Dad's Struggle with Control and Intimacy

I've always been the one in control, not just at work but also in my personal life. When I met Sarah, a free-spirited woman who craved structure, something clicked. We fell into a Daddy/kitten dynamic where she plays the part of a little girl and I take on the role of her father figure. It's intense, exhilarating, and sometimes painfully intimate. But lately, there’s this nagging feeling that I’m not just guiding her; I'm imposing too much control over every aspect of her life. We have these heart-to-hearts where she tries to push back, but I end up dictating how things should be instead of finding a balance. Tonight, as we were playing, it hit me hard, I was starting to feel like I wanted to keep her small and innocent forever, despite knowing that's not healthy for anyone involved. Does this mean I’m slipping into something dangerous? How do I ensure we both grow and stay happy while maintaining our unique dynamic?
