Doc's Dirty Little Secret

I always thought my medical training would give me a unique perspective on relationships and sex. So when I started fantasizing about being restrained during foreplay, like in those old-school, clinical restraints used for blood pressure checks or IVs, I wasn't surprised by the kink itself as much as by how intense it made everything feel. It's weirdly soothing to be vulnerable and unable to move, knowing you’re completely at your partner’s mercy for a moment. But here's the funny part: my girlfriend looks at me like I'm crazy when I bring this up. She doesn't get why anyone would want that kind of control or helplessness in bed. I guess it’s just one more way we differ, but honestly, I find the whole setup so charged and intimate, it leaves me breathless even thinking about it. Have any other docs played out fantasies involving clinical equipment? Is this common among people who have professional contact with such tools, or am I totally unique in this?
