Secret Fantasies at Work

I've been working as a bartender for almost ten years now. It's not just a job, it's my life, the people I meet, the drinks I serve, and sometimes the conversations that lead to much more personal moments. Recently, though, something changed inside me. My partner doesn't share this particular kink of mine; it involves role-playing situations where I'm in a position of power over someone, using my bartending skills as a way to control or seduce them. It feels wrong and right at the same time, intoxicating and terrifying. Lately, when I meet new patrons who seem particularly intrigued by me, an urge arises within me to act on this fantasy. But every time I get close to crossing that line, something holds me back. Part of me wonders if it's even normal to have such intense fantasies at work. Am I overthinking things? What should I do?
