wenn er die fehlende Fähigkeit des Jugendlichen zur sexuellen Selbstbestimmung ausnutzt

This paragraph is the important one. A court must first rule the teenager was not mature enough to bang an adult. Courts have ruled sexual inexperience alone is not sufficient to convict someone. The inability of a 14 year old to consent must be proven in order to convict an adult for banging a 14 year old.

Nope, not in Germany. A 110 year old can legally bang a 14 year old, as long as they don’t have a position of authority over the teen.
