Hiding/covering yourself while waiting- yes or no?

For all you guys who either had to stand in line for a group physical, wait your turn during a joint physical ( with a sibling), or wait in the exam room with a parent and / or sibling until the doc arrived- did you try to cover/ hide your genitals until it was time for your exam, or did you just stand / sit / lay there fully exposed?

For those of you who did cover up, why? For those of you who didnt- did you find the situation enjoyable, or were you simply resigned to it?

When I received a group physical in my graduating year at university there were a dozen boys scheduled at the same time and we were told to strip completely before entering the large open exam room where we then moved from station to station for each part of the exam. It was a bit embarrassing to watch each other being poked and prodded in full view of each other especially since most of us got erections at some point but I was used to being naked in the change rooms and showers ever since Junior High School so I just resigned myself to it.

When I had my MEPS physicals, (I had 2 since I was in the Delayed Entry Program, one just before I went into my senior year in High school, a repeat one when I actually was sworn in and left for boot camp a year later.) We didn't so much intentionally cover up (We were in underwear) as it just seemed that the most practical and convenient way to carry the file from station to station happened to be carrying them at groin height. (That's about the level the desks came up to.)

I have never been brave enough to not cover up. It's intimidating for me and just so dang personal.
