I have never found full-frontals of Doran Propp and Frank Zeuch, just more posing suits with pubes showing. I would consider that an unfulfilled temptation. My next photos in the shoot would be full-frontal, as to not let my fans down.
Larry Scott was a very well-known bodybuilder who also was photographed by physique photographers showing about an inch of a thick patch of pubes at the tops of his posing suits. Drives me crazy!
