How to tell if someone is kinky/freaky?

Just curious, because I consider myself kinky/freaky, but for fear of judgement I do not publicly showcase myself as that. Still, I am unsure if people could still be able to sense that.

Have you been able to teka or agak2 if someone is kinky just by looking at their appearance/behavior/how they present themselevs?

Merdeka to all btw!
