What's the longest period of time that you ever stayed nude or in your underwear during a physical exam?

5 - 10 minutes in my briefs but it always feels much longer especially if when having to sit on the exam table! I hate that crinkling sound and how my skin feels coming in contact with it. Then there is the anticipation of when there will be a knock on the door. Each foot step makes me wonder is it now? Thankfully, I am not lying on my belly with a rectal thermometer inserted waiting for the doc to appear as I did when a child or teen!

How bout most of the day? Been nearly 50 years ago but nearly every 18 to 24 year old American male had to undergo a group pre-enlistment physical exam at a draft board examination center known as a MEEPS. The fashion de jour during the half day medical portion was typically briefs, but some centers still processed examinees totally nude. Others centers insisted that "draft board delinquents" remain nude as they were less argumentative and more docile when told at the end of the day that they were being immediately conscripted rather than merely being sent home to await their selective service classification.

As a medic, I fortunately was assigned to assist at a MEEPS for only about 3 weeks total, but doing 9 month assignment to an Army recruit training base, I spent more days doing the recruit reception physicals than I care to remember. Depending on the number of men received, whether the recruits were enlisted or draftees the attire was the same. Only wearing smiles!

That's not entirely true. Go to a sauna in Sweden and they will generally be separate male and female facilities. The one I visited in Finland had both single sex and mixed facilities, but you were required to wear swimwear if using the mixed facility.

I understand that part of it. What I'm saying is once the boys and girls have seen each other in their Speedos and bikini, seeing each other in their underwear should be no big deal.
