Rectal examination in the presence of a parent

In my childhood, I had a regular genital examination at the pediatrician. This was done in the presence of my mother. When I was older, I was ashamed of it. It wasn't embarrassing that my mom saw me naked. It was embarrassing that I was examined in her presence like a small child.

I have never been examined through the rectum in the presence of a witness. Have any of you been examined in childhood through the anus in the presence of a parent? or later in the presence of a witness? How did you feel? Was it very embarrassing?

@Reman Yes, it happened to me twice when I had appendicitis — a digital rectal exam was done to confirm the diagnosis reached by other signs and external abdominal examination — nowadays they'd use ultrasound, I think. Both examinations were done in front of my mother. Given that I felt really sick I did not have time to feel embarrassed on the moment.

I later thought that the adults present, especially the doctor, could have had the common courtesy to tell me in plain language that I'd be getting a finger up my derrière. (The thing had probably been discussed in grownup speech, at least for the first exam.)
