A few years back a friend of mine was having some issues in the rectal area, and he knew he would have to see a doctor, but he wouldn't make an appointment unless I agreed to go with him to the doctor.
I wasn't sure a doctor would allow me into the exam room with my friend, but I agreed to go, and take my chances.
Fortunately, the doctor had no problem with me in the room, if that's what the patient wanted.
The strange thing was that this doctor seemed to conduct the exam in a way that was completely humiliating to my friend.
He started out having my friend remove his shirt and shoes. Then after stething him and listening to his abdomen, he told him to remove his jeans and underpants. He was left standing there with nothing but his socks on. My friend and I were trying not to make eye contact. I could tell he was absolutely embarrassed.
After inserting his finger into my friend's butt in several different positions, bent over, left side on table, he finally brought out the stirrups and had my friend lie on his back and put his feet in the stirrups. I can still see the look on my friend's face as he was lying there with his legs spread wide open. I didn't want to watch, but I had to.
Before he inserted his finger this time, he asked my friend to "bear down". I think my friend thought if he didn't do it, the doctor would not know the difference. But, unfortunately, the doctor could see that he wasn't doing it. So the doctor repeated himself: "Come on, young man, push down like you're taking a poop". Now my friend couldn't avoid it. As he was trying to push down, the doctor started inserting his finger. All of a sudden there was a loud release of air as my friend started to pass wind. I could hear him groan as he realized what he had just done. The doctor paid no attention and continued to probe him. As he started to withdraw his finger, I could see my friend's face and body, trying to tighten up to make sure that didn't happen again.
So, in my opinion, I feel most men don't like to "bear down" because it is very likely that they will have an accident. I've heard stories of guys bearing down during a rectal exam, and actually have a turd fly out. How much more humiliated can a guy be?
