There are many stories like this; there are even cases where someone got convicted of child pornography for sending nudes of themselves to their {boy,girl}friend.

It's bonkers. But it happens. Unfortunately all of this has become something of a taboo, but teenagers having sex is ... kind of normal. What exactly is and isn't acceptable is very hard to decide as a general matter, and far too often any conversation is shot down with "pedophile apologist!" or, in this case, baseless "you must have done something wrong!" assumptions.
