Feeling Lost in Caregiving and Little Space

I'm 45 and have been married for nearly two decades. My wife and I have always had a deep connection, but lately we've stumbled into these strange spaces of play and care that feel both thrilling and terrifying. Some days she takes on this caregiver role, where her instructions are absolute, how to dress, when to eat, it’s like being under a spell. Other times, I'm the one who wants to regress back to childhood, feeling small and vulnerable, yet safe in her protective gaze. It's not always easy; there are days I struggle with these roles because they clash so sharply with my identity as an independent adult. Yet, when we're fully immersed, it feels like a secret code that unlocks new levels of intimacy and trust between us. But here’s the thing: does everyone else experience something similar in their relationships? Am I overthinking this or is there more to explore than just following rules blindly?
