I would imagine that YMCA's that are fairly established would have the gang style showers of another age. Most YMCA's now do not build new facilities but either borrow facilities at a school/college or they rent/lease/buy old gyms that have failed. The last Y that I joined did have all male nude swimming every morning at 7:00 AM. You would go there and all of these elderly men would be in the pool. They were in great shape having worked out at the Y pool all those years. It was seen as the norm and was not erotic in the least. Not due to the men's ages but to the attitude. At firstI always wore a suit but they looked at me a bit odd. So I went nude. Great camaraderie there.
