Okay, let's say said teenager gets the shot and knowing she can't get pregnant, whores around with anyone who wears a jock strap (I know, in some circles that wouldn't necessarily be a man). So shot that will protect her from what sexually transmitted diseases? Because a GIRL on birth control sees little need for her partner of the moment to use a condom no matter how many times they're told about "safe sex". Not to mention, show me a guy who will use a condom if he doesn't have to.
