i would call it a terrible accident
sorry, now trying to be a bit more serious, its also something that happens here, and we can only complain about the rules of the society we live in, the real issue here is that parents should give all the information to their sons in order to prevent such terrible mistakes, although they are more likely to pretend that nothing will happens because their sons are to young for such things, and then they cant even imagine how ironic life can be when it happens, we should be here discussing if its to early or not to have sex with that age, the fact is that they do have sex and we cannot pretend that nothing happens, so if they do lets try to minimize the risk of getting pregnant or even worst prevent sexual infections
