Advice

You are a young, female teacher from "up north."  You teach high school Biology in a small Delta community with one church for every 30 residents.  Several of your female students have discreetly asked you for advice on various birth-control measures.  School district policy is to promote abstinence-only.  Furthermore, the community, spurred on by the churches, and in spite of the high teen pregnancy rate, is strongly in favor of abstinence-only measures.  You trust the teens to keep your confidence, but at the same time they are teenagers and teenagers talk.  You are worried that if you are discovered to have contradicted the official school policy, and the unofficial community norms, you will be ostracized and perhaps even lose your job.  What advice do you give?
