The only thing right now that I can say after seeing that the Alaska court system is about laws and law only and not about what is right or wrong,  is :
Parents.......teach your girls to respect their bodies and have enough respect for themselves not to have sex with a boy just because he says he likes them.  OR to get the boys to like them.....  Or because some of the "other girls brag about doing it"    Teach them that even if it nearly goes "that far"  they can still say NO to the boy and if he doesn't like her after she says no then he's not worth her time and heartache.     Teach your boys to have respect for the girls and never pressure girls to have sex with them. You can try to teach your kids to tell you everything, but having been a kid myself, and having had my own kids, after a certain age most kids don't want to tell their parents much about what they are up to until they are grown. Instill in them from birth to respect their own bodies and others and resist peer pressure.
