I don't believe today's world is any less safe than the world has been before, however we are in a position to ensure that our children are better protected by arming them with the knowledge they require to protect themselves.  Talking to kids from an early age in a frank manner about their bodies, using correct anatomical names and allowing for free speech about these topics in the home will make it easier down the track when they are teenagers.  Find out what programs their school provides in sex education and make sure that they are up to date and down to earth, some are still out of the dark ages.

Giving pamphlets, books and links online to them are a great start, then you can discuss the information with them and ensure that they understand it properly and ask them what action they intend to take to avoid unwanted pregancies and sexually transmitted diseases.  It is good to get some protection and leave it on hand, rather than running the risk of a disaster happening.  Some people may see this as condoning teenage sex; however each household has it's own rules and regardless of them; if your teenager decides they want to do 'IT' they will.  If you don't feel you are getting through to your teen, take them to a professional to confirm all you have said, one mistake on their part could change their life forever... Or end it prematurely.
