This is a running theme in our family. My brother and sister-in-law have been spying on their 16 year old daughter for years. They were getting pretty high tech and spending a boat load of time trying to monitor her life. They just recently found out she was having sex, shocking for a 16 year I know, and went off the deep end. They pretty much want to have the lock and key to her body and as we all know this is not the way to go about it. Forcing teens to do anything will almost always get you the opposite reaction and I can only imagine how ugly it will get now that their whole spying ordeal is out in the open. I would be shocked if she is still living with them in 18 months. As a parent, I would hope to instill good enough values that would keep my kids out of harms way. Having sex at 16 is not exactly strange behavior.
