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.
Most Eastern and Central European countries have more approachable women than the west, because flirting is still part of normal romance there. If you’re funny, hygienic, tasteful, and flattering, but not creepy or pushy, you will score some dates (and some respectful rejections). You’ll find they’re very straightforward and will just tell you what they want, there won’t be any guessing games as such.
They will be expecting you to dress well and take them somewhere nice, and pay for the bill. You’d also be expected to meet the family if things start going well, and this will be tricky if they don’t speak English or you don’t speak their language. However if she likes you and speaks highly of you, then you’ve just been adopted into a large extended family who will unconditionally love you so long as you treat her well.
