Newly Discovered Kink

I recently discovered an unexpected kink that has left me both excited and bewildered. As a doctor, I'm well aware of the importance of boundaries and consent in any relationship or dynamic, yet this new aspect of my sexuality is challenging to navigate within those frameworks. During a recent session with my long-term partner, we found ourselves engaging in an activity where I took on a mentor-like role, guiding her through a scenario that was both intimate and slightly uncomfortable for her, but entirely consensual. It felt as if I were nurturing a younger mindset in her while also taking on a protective stance towards her emotional and physical well-being. This dynamic has left me questioning how to explore this further without compromising the trust we've built. Is it normal for adults to engage in such dynamics, or am I overthinking everything? What advice do you have for someone looking to responsibly indulge in this kink?
