In most of the countries I have stayed/lived, cross-gender interactions are more like a mind game than anything else. Women are neither supposed nor encouraged to be flirty or openly approachable. Wondering if there are countries where it’s not such the case as a cultural specificity.
It sounds like you’re experiencing this reaction because you make women uncomfortable, so they’re worried about giving you any incling of an idea they might be interested in you, because they can tell you’re the type of person to not leave them alone once they do. So no, in no country you will find flirty women until you become a nice fun and SAFE person to flirt with.
