How common were erections in the lineup at group male physicals?

I've never been through a group physical myself, so I have zero personal experience and therefore no frame of reference.

Over the years I've read a lot of conflicting accounts, from guys being so worked up at the prospect of being intimately seen and touched by another human being that their weiners pointed skyward, to guys being so uncomfortable and embarrassed by the whole spectacle that their wangs practically shriveled back inside them.

What has been you guys' own personal experience with this? What happened to you personally, and what did you observe among your peers? What thoughts and emotions went through your mind at this time? How were the folks in charge acting?

A couple of examples from my experiences:

1. Military induction physical / MEPS: we were mostly in our skivvies and carried our clothes around in plastic laundry baskets, mostly in front of our crotches, so while I doubt there were any reactions, if there were, they were probably hidden.

2. At Parris Island for recruit training, for the first month or so, after physical training we would go back to the squad bay (barracks), shower, and then stand on line in front of our racks (bunks) wearing our shower shoes & our towel wrapped around our wastes. Then an officer would come through and stop in front of each recruit. When he did, you were supposed to remove your towel and hold it over your head and slowly turn around in a circle, citing any injuries or physical issues. Ostensibly they were looking for infected cuts or rashes, but they were also looking for first shaped bruises or other signs of abuse. Since you are standing at the position of attention, your field of vision is very limited. So I never saw anyone with an erection, but I'm petty sure one guy did have one, based on the reaction of the officer and the DIs (glad I want him).

3. Reminded of one incident in Jr High gym class where the "coolest kid in the class" popped an erection in the shower. He tried hard to hide it and knocked some kids over a he ran from the shower to his locker with everyone laughing at him.

Our group physicals in high school, for sports, were not line ups, they were station-to- station, but you would occasionally see a semi-hard on.

That would be weird lol

Yes for my participation in high school and college crew the line up took place but there were no erections. One is too nervous!
