One of those strange things about the EU - there were never moves to harmonize age of consent across Europe. It's much lower than you might think across Europe anyhow - at lot of EU states have 14.
OT - how would you feel about harmonizing the age of majority for all things:
Sex, voting, driving, drinking, smoking, contractual obligations, criminal offences, marriage etc. There are always these arguments "why can I drive/have sex, but not vote?"
Not sure I'm in favour, but I were, I'd put it at 17 with some kind of Romeo & Juliet law for sex down to 15.
