I think what he meant, Pumpkin, is that you're not seeing his point.
The issue is, a girl, like yourself, at the age of sixteen, whose in love with this one guy. You love him so much that you decide to snap some sexy pictures of yourself. Let's assume, you send it, and like a good boy, keeps them to himself. Unfortunately, bad luck happens and you are the one discovered.
Congratulations, you, Pumpkin Seeds are now the equivalent of a child molester. Go straight to Jail, do not pass go, do not collect $200. You've been caught, and you WILL be prosecuted for Child Pornography. You WILL be on the Register. People WILL know when you wish to move into a neighbourhood, they won't know, and don't fucking care WHY, you are on the Registry for Child Molesters, and they WILL try and make your life a living hell until you move away. Good luck getting into that neighbourhood in the first place, because no one will EVER hire you. Not even McDonald's will take you. And don't expect to finish school, anyway. Which means Social Assistance, but that's not going to happen either. Criminals are not allowed on that. So, no income, ever. No feasible way to get a decent home. Hell, I know the local shelters (in Canada, mind you, the U.S. might be more lenient, but I honestly doubt it) won't let a convicted child molester in their doors. Remember, that's what you ARE. The law makes no differentiation as to how you got on the Registry, just that you are. So now, you can't even get a roof over your head.
So your future, such as it is, is pretty much either requiring you to go underground and change your name. Or, more likely a life of prostitution to some pimp, or a back alley porn actress, who hopefully doesn't get involved in snuff films. That's pretty much the three options you have left for your life.
And all because you decided to take a picture of your underage self, on your bed, on all fours, maybe a side shot, nothing more than a little bit of boob showing, and sent to the boy you loved. Who probably is facing the same damn problem.
