Polish men are not that different to any other men.
But they are, it's a matter of upbringing. At least that's how it was when I was young and still living in Poland. The boy always opened the door and let the girl in first. After the cinema, you always walked the girl home. The bill was always paid in full and not splitted. Those were obvious things. Only the kissing on the hand was gone.
Ps. Not to mention giving up a seat to old grandma on bus.
