I can see the pros and cons to this. The good thing, is that they're saying, hey, if you are going to have sex, make sure you use protection. The bad thing to me, is similar to what others are saying. It seems that it would encourage younger people to go out and have sex when, imo, teenagers really shouldn't be due to their not learning responsibility yet at that time, and shouldn't be boggled down in case of an unplanned pregnancy.
I know I didn't really answer the question, since it seems I'm for and against it, but regardless, if someone wants to have sex, he or she more than likely will, either way.
