What are relatively safest countries/places to be an exhibitionist?

[Kekkaishi]

Excluding nude beaches and designated places where you can be an exhibitionist…

There are lots of videos of people jerking / fucking in public - restroom, showers, beaches, streets etc...
However, I also read many comments describing how dangerous can it be, that you can get caught and even be registered as sex offender.

I am not exhibitionist personally, but I do find myself wanking at the stall of a public restroom from time to time
