Proctoscope exam

I've had proctoscopic exams several times over the years. I agree with the other posts that they are not at all painful.

I fortunately/ unfortunately have no experience with this, so correct me if I'm wrong. But isn't an anoscope approximately 3"-5" long and a proctoscope/ rectoscope 10"-12" long, both about 1" in diameter?

@BenDover Here's a link with a photo that compares anoscopes, proctoscopes, and rectoscopes.

I have a Female Doctor who does my Proctoscope. She is very gentle. I always get an erection when she does this to me.
