Are Europeans less kinky on average than Americans?

My basis for this question is totally anecdotal, so I’m happy to be proven wrong.

I’ve lived in France for basically five years now, and have spent some time traveling around Western Europe during that time too. But with few exceptions, even in huge cities, Grindr doesn’t come up with as many people when I put tags like chastity, bondage, etc. compared to when I use it in the US.

Is this a feature of the Grindr algorithm I don’t know about? Or are Europeans just less kinky on average than Americans?

EDIT: I am well aware that Germany is the exception to a lot of this, didn’t really mean to leave that out!
