I am male and have been going to the same doctor (female) for physical exams every year for at least 10 years. When I go in for a physical, she has me naked except for the little gown that is worn open in front. At the end of the exam, she does a prostate exam (standing up and bent all the way over) and testicle check, at which point the gown is hanging loose, so she sees everything I've got. Because I have seen her so many times, I am very comfortable being naked around her, and don't even give it a second thought.
My wife is always present during the exams, and when the exam is over the doctor is normally very chatty and the three of us talk about my health or whatever (We are all the same age).
I last went in to see her about a month ago. After she checked my prostate, she said "Ok, you can get dressed from the waist down now." And I was surprised that she could not look me in the face after the exam (she kept looking down at her notes) and suddenly seemed in a hurry to leave the room. She gave me a sort of embarrassed look and practically ran out of the room after filling out a couple of prescriptions for some maintenance drugs that I take.
Granted she had just got an up close look at my ass, but I was still surprised that she looked downright embarrassed, to the point of not being able to look me in the face. I mean, I do this every year with her, it's not as if it is something new.
Have you ever been to the doctor and felt like you embarrassed your doctor? It was just a really strange experience and I am still wondering what happened...
