Casual relationships in Poland (at least at the beginning)

Hey, Ive just moved to Poland few days ago, and I was wondering what exactly expect the women here. I mean, I understand that you can be looking for love, but how the hell am I gonna know if I like you beforehand. Im not gonna lie, right now, since I ve just moved in I dont really look actively for a marriage, but ofc I dont close that door, if happens it happens. Ive seen in tinder that almost 100% of girls has the "looking for a relationship" flag, so Im curious about what they really expect: exclusivity from day 1? no sex until marriage?

Im pretty lost in that sense because in my country is completely different the dating game. I don't like one night stand but I like to keep things informal until I know the person and we want to move forward the relationship.

Thanks in advance!
