I don't really have a preference. Both kinds have issues.
I was married to a polish man, but now I mostly date American men. I think, they have less expectations when it comes to cooking, cleaning and other domestic chores. Polish men tend to think, it's my job... Also, polish men do not like it when their girlfriend (wife) has her own circle of friends. They get jealous and suspicious.
However, polish guys are excellent in fixing stuff around the house. They seem to be born knowing how the plumbing and electricity works

American men have to call a plumber when the faucet leaks (and a washer needs to be changed). However, I don't have my mind set on neither and I'm open to date both.
American men like to go out, movies, restaurants, trips and seem to be more generous. I like that.
