Well
this club (named in English Castle Waterloo) has several different "evening themes" to choose from.
One of them is called now "nude party". A long time ago the theme was named naturist evening.
My wife chose this topic. Her reasoning was very simple: 'It's about having sex. Taking your clothes off, putting them on and taking them off again, you can make it easier by just being naked."
It used to come with the warning 'for experienced people'. Now it just says 'for active couples and single men'.
I can still remember the first time we queued to get in. Only single men. So my wife asked if there were more couples. The answer was, of course, yes.
Later that evening I asked the management about the number of visitors and the ratio of couples to men.
The number of visitors was over 200, of which about 40 were couples. A simple calculation shows that of the 40 couples, there were 120 single men.
Not counting the male partners, there were 3 single men per couple. On average....!!!!!
That first night, after less than five minutes, I asked my wife for the first time to stop two men groping her everywhere. I was afraid she would ask me to go home. Her reply (with a big smile):
'Let them, can't you see I'm enjoying it.
It became her evening and I just had to watch.
All subsequent visits did little to change that.
