It was partly social consequence, and party not wanting to be late for class. Since no one used the showers, the ones who did were usually considered weird or creepy. Even more so when the showers are open designed and you are naked in front of the entire locker room(high school only I think). The bigger half though is not wanting to be late for class. Most schools operate on a 5 minute timer between classes and even being a few seconds late is grounds for punishment. Being that you rarely ever get into the locker room and dressed back into your day clothes before the class is over, you're already pressed for time before you even consider using the shower.

Yep. When I went to high school, literally no one showered. I never saw a single person shower after gym class.

The thing that baffles me about it, is that if you're going to do physical activity like that, a shower after should be mandatory unless you are going home. Otherwise it's pretty gross. The result will be people not trying hard in gym, or people being unsanitary.

I guess this is all because we're ashamed of our bodies or afraid of sexual perverts? What the hell happened to us that we are this way?

I would have been afraid to shower in high school, the way it was. I have since showered in front of many strangers in the military and nothing bad has ever happened to me as a result. If you do have something odd happen, then that should be dealt with. But come on man, high school is not a prison. You are pretty safe to take a shower there.

tl;dr our society would rather be dirty and gross than see the naked bodies of our peers or be seen.

Would partitioned showers help with this problem?

Middle schools already have partitioned showers. At least mine did, I imagine most others that have them do as well. The biggest issue with the showering are the time constraints. The social stigma is present, just in a minor fashion. Being late to class trumps all else.

My middle school did not. No doors on the bathroom stalls either.

The time constraints are imposed by a school administration that assumes you will not shower or does not want you to shower. The real problem is people are afraid of nudity.
