Sometimes, hearing about medical procedures/exams/tests that happen in a real setting turn people on. On a personal note, the more authentic the exam is, the better it feeds my kink. However, I echo that real exams/procedures are not typically fun and are most likely done to find out if what is happening is bad or good.
For example, I have had to have two transvaginal ultrasounds recently (both within the last six months). At the time of the initial ultrasound, it was nerve-wracking and generally uncomfortable, but a necessary test. Something bad WAS found and treated medically with me... The follow-up scan was equally as anxiety provoking, mainly because I wanted to learn that what was going on with my body was "ok" and that the medicine I was put on had worked and done its job.
Now, there are some procedures and tests that in my mind are thrilling; however, when I'm having them because of a medical necessity, they are NOT kinky and they are the furthest from being kinky to me. That's not to say that afterwards I sometimes think of certain procedures that I've had and replay them in my mind once I have peace of mind that my body is ok and they BECOME somewhat kinky.
For me, when I'm in a doctor's office, it's strictly business. I'm there to have a problem solved/looked at/etc.. I'm not there because the kinky side of me needs satisfaction.
