I am a dr of law in Uniwersity of Gdansk. My subject - substantial criminal law. In Poland the age of consent is 15. It is 15 from 1932 and now. None of us speak Polish, so we must assume this information to be accurate.
Source is noted above.
I would like to confirm that the translation in the second e-mail for the Polish Age of Consent page is accurate, however there is one minor detail missing. The translation simply states 'up to 10 years', and does not include that minimum time.
