It may seem silly to address a topic that many of us had explained when we were very young. Unfortunately, very few of us have had it explained well, leaving a good many with no idea what the birds and the bees really mean to our everyday sexual lives. Every day someone at Scarleteen asks if this, that or the other thing is a pregnancy risk, or how they can tell if they are pregnant, or how they can even get pregnant in the first place. It isn't stupid or immature not to know the answers to these questions. It is only foolish not to ask them when we don't know the answers, or to assume we'll just be "lucky," and so never try to learn.
