My Patient's Secret Sighs

I've been in nursing for over a decade now, but it wasn't until about six months ago that I found myself attracted to one of my patients. Let me be clear: this isn't just a regular crush thing; we had an arrangement, both of us being part of open relationships and understanding the boundaries between professional duty and personal desires. It was all consensual and kept entirely off the clock. He's in his mid-forties with greying hair and a rugged look from years of hard work. There were moments when I would check on him, and there it would be, that secret sigh or the way he looked at me when the rest of the world faded away. It wasn't just about sex; it was this deeper connection that made everything feel both taboo and utterly right. Then we started with some roleplay scenarios. We wouldn’t touch each other in his hospital room, but there were these moments where I'd slip a note into my pocket before leaving, something he had scribbled for me about what we could do later. It was intense and made everything between us even more charged. But here's the thing: does anyone else experience this kind of deep connection in such unexpected places? Is it just because both of us are adults who know how to handle consent and desire, or is there something more going on that I should be wary about? Sometimes I feel like I'm walking a fine line between passion and professionalism. What do you think? Am I the only one this happens to?
