Discovering My Kink Late in Life

I've always thought of myself as pretty vanilla when it comes to relationships and sex. But recently, I stumbled upon this kink that I never knew about until now, and oh my god, it's been a revelation! I'm a stay-at-home parent to two amazing kids who are both 18+, and for some reason, the idea of being in charge has always fascinated me. Last week, during one of our regular date nights with my partner (he’s forty), something clicked inside me. We were playing around, and I found myself getting this strange rush from pretending to be a strict authority figure in our intimate moments. It felt so good, like I was finally tapping into some deep part of myself that had been dormant all these years. The thrill of being the one calling the shots, even if it's just for a bit of role-play, is unlike anything else. But then I started to wonder, is this normal? Am I just late in discovering my kink, or is there something fundamentally off about me enjoying such control and power dynamics? It’s so new that I’m still trying to process all these feelings swirling around inside me. Anyone out there dealt with a similar experience of finding a kink later in life?
