Wife and I have been to Hezemeer in Belgium earlier this week. It was pretty crowded, but there was a good mix in age. Only about 20% was 60+, about 10-15 % between 50 and 60. The rest younger. Also about the rate of man/women was about 50%, with a small majority of women.
All this has changed a lot over the years. I can remember the 1st few times we went there, little over 20 years ago. I was mid-20, wife was about 19 or 20. Majority of the people (80% or more) were 65+ and a big majority of them were man. Imagine the attention a young perky lady got back then

Reading through this topic,, I'm glad to read all of your experiences. But to be honest, to me a public sauna is one of the least erotic places. It probably has something to do with the fact that all are naked in the sauna cabins and most don't even bother to cover up outside of the sauna cabins. Too much nudity kills the mood a bit, specially when there are lots of people around you rather wished you hadn't seen naked
. But showing off my beautiful wife does gives a little thrill each time.
