Do you know how creepy you sound, man? Being an "It's OK for 13-Year-Old Girls and Boys to Send Naked Self-Portraits" advocate isn't something you want to yell from a rooftop.
Besides - is it legal to have a beer when you are 13? No. Smoke cigarettes? No. Drive a car? Watch an R or X rated film? No. Send X rated photos of your self to anyone? No! A lot of kids will still do all those things before they a legal, but it's still a law.
If they only reason for a sexting law was too keep digital photos of children away from sick perverts like yourself, then I'd say that is a damn good reason.
"No-one gets an ironclad guarantee of success. Certainly, factors like opportunity, luck and timing are important. But the backbone of success is usually found in old-fashioned, basic concepts like hard work, determination, good planning and perseverance" -- Mia Hamm
