We have a special chemistry, but I would like to know the dating customs of his culture.
Polish males are not a homogeneous race which shows the same characteristics, to be put in a seperate specific group: "Polish males."
Polish male culture is open and varied - it makes dating customs as multiple as many males there are.
The Polish male dating behaviour depends on many conditions: his education, religion, wealth, character, humour, upbringing, self-esteem, attitude to women, etc etc etc.
My advice: don`t expect anything special from him just because he is Polish. Males are always males. Treat him like a male, i.e. be cautiuos and don`t believe any of his sweet words.
PS. If you want to keep him for a longer time, you`d better abstain from too intimate relations for a few first dates/weeks/months if possible. He will suffer but will respect you more then. Polish males can be still very traditional, they are fond of women who respect themselves. So, don`t pay attention to his male begging or implorations ha ha ha ha. However, let him know it shall happen in some nearest future, don`t deprive him of this hope. Make it a game in which he feels like a conqueror who must work hard to get his booty. He will appreciate it more.
I think this is a test that wise women should apply on their men. If the latter are willing to undergo it, then it means they are worth something.
