I've got a hypothetical situation for you guys that someone might actually know the answer to.
Say you made an amature porno of yourself and someone else, when you're a minor, like... 16, yeah... and your partner is over 18. Well, if you put said video in storage, and end up uncovering it years later, when you're an adult, are you in possession of child pornography (in legal-ese, "recording the sex act of a minor")? And can you be charged with possessing such a thing, and prosecuted, despite the fact that it is YOU whom were the minor, you who filmed it, and you who was more than happy to participate in the first place?
I don't know if it's legal or not... I do know, if I was in a hypothetical trial for said hypothetical crime, I'd ask for a jury. Legal or not, who'd actually convict someone for something like that?
