My first adult experience with CFNM was at a physical for the draft during the Vietnam War. We walked through each station of the exam in our underwear in a single file line. When the line moved past a wall, I saw 2 ceramic trough urinals in an "L" formation that each served 3 or 4 guys. There was a nurse by the one side of the urinals handing each guy a jar from her cart. The guy took a spot at the urinal to provide a urine sample and then gave it to the nurse at the other end of the urinals who placed it on another cart. I remember thinking that it seemed strange that these 2 women sat at opposite ends of the urinals all day long while young guys peed. When my turn came, I got the end spot right next to the lady who collected the completed samples. I pulled Junior out of my briefs and stood there waiting for the flow to start. I could see the nurse looking at me (wondering why I didn't pee right away). After a delay of about 30 seconds, I began to piss. Once I started peeing, I filled the jar and kept peeing into the trough. It was exciting to pee that close to a woman that I didn't know.
The next station was the hernia and anus check. The doctor examined 10 men at a time. He directed the next 10 men in line to remove their underwear and stand in a line side by side. There were women behind him working at desks who could easily see each group as they were examined. Bending over to get the anus checked was probably the worst part of it.
In retrospect, the women who worked there saw this stuff every day, and were probably indifferent to it. There were some young nurses where they took height, weight, blood pressure, etc., but the 2 women at the urinals were elderly. It was probably done intentionally as young women at the urinal station may have caused the guys to become erect and slow down the process. L.O.L.!
