Child rape then if terminology bothers you that much. Either way whether they're 3 or 14 they're under the legal age of consent and it's a crime.
You're using the word child when it isn't applicable to a 14 year old teenager. The terminology doesn't "bother" me, it's just incorrect. I don't disagree with the law or think it shouldn't be a crime, but it's not pedophilia. The difference between this and for instance Ian Watkins, the ex-Lost Prophets singer is night and day, yet we're applying an equivalent term when one crime is magnitudes worse than the other, at least in my opinion.
