I’ve talked to a lot of men and women of the generation before me who practiced swimming at school in the nude (segregated, boys and girls). This would be a generation before “sexuality and LGBT [were] all out [in the] open” - in other words, during the past where no one talked about that (apparently). That generation would seem to be among the people in this thread talking about how nudity in the lockerroom is no big deal.
I don’t know what you are trying to say, either.
When the local high school ended gym showers, the newspaper article stated it was because bacteria requires time to grow and there would not be enough time between gym class and getting home and showered for it to be a problem.
