First off, I don't know if she's already married, (she doesn't wear a wedding ring). Is this normal in Poland?
It doesn't mean a thing.. If you are determined enough, you can have a woman wearing wedding-ring as well..
Second, I don't speak any Polish and she only speaks a little English so how would I ask her?
If you want to impress Polish lady, don't use Polish language in her presence, you'd better play a role of rich foreigner... But if you really must do it, choose one of these options:
1) Chcesz się bzykać? (khtzesh s-ye bsikatz?)
2) Twoje krągłe kształty doprowadzają mnie do ekstazy (I am too lazy to transliterate it)
3) Ile bierzesz za szybki numerek? (eele b-ye-zesh sa sheebkee noo-merek)
