A family member retired as a paramedic with a metropolitan fire department. He once seemed totally shocked to have made a call where a man, who'd had an encounter with an alligator, was on scene wearing a pair of overalls with pink panties underneath. I remember the family member telling me and my wife the story, being totally shocked at the incident. The truth is that I wondered, when he told me, if he had suspicions and was feeling me out for a reaction. He brought it up again later, still baffled why a dude would wear pink panties. It was clear then that he had no idea that I was wearing panties at the time.
So, no, not all medical/ems personnel have seen it all. And, even if the individual doesn't say something to you, that doesn't mean he/she is not discussing it, in an anonymous manner of course.
