Vienna has a very long and traditional society regarding kinkiness.
This is the reason why things like the Life Ball etc. are founded there. I can't imagine any other city for that.
I grew up in Vienna and seeing Dragqueens, Gays, Kinky, Fetish people was just normal for me.
In fact, I really liked it because it was just normal.
After I moved to another country, I missed this kind of open minded atttitude.
So that shouldn't be a problem, just in case these places are not closed because of Corona.
