Confessions of a Nurse and Her Secret Fantasy

I've been with my partner for ten years now, and we have a strong relationship built on trust and openness. But lately, there's this fantasy that keeps creeping into my mind, a naughty one involving roleplay where I'm the subordinate in a medical setting. It started when I was working night shift and had to perform some intimate procedures on patients who needed help. The sterile environment mixed with the vulnerability of those moments sparked something inside me. When we talk about sex, I usually feel confident, but this fantasy makes me feel exposed and unsure. I know my partner would be supportive if I told him, but there's a part of me that's afraid he'll think it's weird or that it might push us away from our usual comfort zone. Has anyone else dealt with something similar? Am I the only one who finds the clinical aspect of sex appealing in a consensual roleplay context?
