Not exactly the same pattern, but still a "surprise, surprise" rectal temperature taking, especially as it was not common to have your temperature taken at school exams. I have already posted several messages about my school medical exam, during my last year of high school which took place back in 1969 somewhere near Paris, France. I was 17 and a very shy boy.
The boys in the class were quite excited because we got that year a new school doctor, who was a lady aroung 30 and was quite attractive. I remember she wore a miniskirt on that very day.
The exam ended with my pants down to my ankles standing in front of the doctor sitting on a stool. She checked my penis, moving the foreskin back and forth, and my testicles. Then, with a gentle voice and a big smile on her face, she said: "turn around" and then, without any notices, she parted my buttocks and slid a thermometer in my rectum. Then, I just had to wait sometime (one, three or five minutes, I have no idea) with the thermometer in my ass, the hands of the doctor on my buttocks, and the school nurse and the school psychologist, present during the exam, watching the scene and not missing anything of the show
As a teenager boy, I felt humiliated, but also aroused, by this situation. As a matter of fact, it was the only time in my life, I almost came to an erection in a medical exam. .
