Anyone remember this old documentary?

Circa 2000, on cable TV, there was a documentary about humanity's fascination with the phallus. I remember segments segued from ancient times to architecture. Suddenly, the camera panned to a guy in a doctor's office waiting room. He put on a deep blue paper gown, the doctor donned gloves, laid him down, pulled up the gown (there was a mosaic) and the camera switched to a close-up of the patient's face, staring at the ceiling, gulping hard.

I wish I could relive watching that scene!

Any clues to what documentary it might have been?

Never saw or heard of it but sounds interesting
