My wife and I usually go to each other's exams. I have seen her in stirrups quite a few times. One Doctor said that he was going to do something different and stuck a finger in her butt, It kind of surprised the both of, although she had had it done before and since. Always causes a tingling in me.
Awhile back she went with me, she had stated that if the Dr (female) did a prostate exam, that she was leaving the room. The Dr. did and my wife didn't. The Dr is somewhat of a friend and my wife even had the Dr. look at my circumcision, which my wife claims is screwed. It was embarrassing to me at the time. Sadly, she doesn't have any anal or med fet leanings.
