nope. Theres one relativeley knew case in Russia about a 13 year old girl and a 10 year old. And theres another one in England with a 15 year old girl who got raped by a 15 year old dude but said it was her 13 year old bf. That case is like, 5-10 years ago. In the article they mentioned the English case.
In the Russian case however, it seems as if the boy is the father.
