Sex Offenses: Statutory Rape Laws in Europe

My question involves criminal law for the state of: Denmark

I'm from Romania, she's from Denmark, I'm gonna visit her this summer and she wants to have sex but I am really afraid, since I'm sure her parents are completely against it so basically we'll have to do it behind their back. Thing is, I know age of consent is 15, in both states, but I am really afraid of a scenario like if her parents find out what she's doing, then they'll sue me, convince her to say in court that it was a rape, and so on and so forth, it's a nightmare I swear. She sent me a lot of naked pictures of herself, and she started to do it since she was 14, if it has any relevance, her parents found out and punished her for that and "denied" any contact to me, or at least they think they did.

Is having sex with her okay? Can anything go wrong? If the answer is yes to both questions, are there any precautions I can take?

Thank you in advance.
