My Secret Kink Revealed at Work

I'm a nurse in my 30s and have always been pretty straight-laced. People know me as the reliable type who keeps to myself and focuses on my work. But there's this other side of me that I never talk about, something that I'm not entirely comfortable admitting even here. It all started a few years ago when I began exploring different forms of kink online. At first, it was just reading and fantasizing, but over time, the fantasies became more real for me. One night, while I was on-call at work, something happened that made me feel incredibly vulnerable, and turned me on. We had a patient in need of intensive care who required constant monitoring overnight. There's another nurse here named Sarah, about ten years my junior, and she has this very no-nonsense demeanor, always professional and serious. Normally, I keep my personal life strictly separate from work, but one night we were the only nurses on duty for several hours straight. As the night wore on, something changed between us. We started talking more than usual, about our days, about patients, and somehow, things shifted. In that sterile hospital environment, under the dim lights of the ICU, I found myself feeling a mix of fear and exhilaration when she took charge over medical decisions, her confidence in her role bringing out this deep-seated kink in me. Now, don't get me wrong, I didn't act on it or suggest anything inappropriate. But every time I'm around Sarah now, there's this simmering tension that neither of us acknowledges but both feel. It's a strange feeling, like being attracted to someone for reasons you can't fully understand or control. I've never shared my kink side with anyone at work before, and I don't know how to handle these newfound feelings. Is it wrong to find the authoritative presence of a colleague in such an environment attractive? Am I being inappropriate just by thinking about it? What do you all think, is this normal? Should I try talking to Sarah or would that ruin everything? How do I deal with these feelings without compromising my professional integrity?
