Planned Parenthoods big line is... "Only you can decide what is best for you.". This is the root of their counciling, and education. Thus, if a kid decides that sex is what is best for them, PP says... Whatever, that is for you to decide. They don't actively encourage sexual activity, but they sure don't Discourage it either.
Wow! You made a great point and then edited it and messed it all up.
