I have gone out with this girl for 6 months and we are 15 and she wants to take our dating to the "bedroom." I'm not sure I'm ready and I don't want an unexpected pregnancy but I do want to have sex. What do I do?

So, you've known one another for a while; that's good. Before doing any intimate physical touching, you should first talk about it. It is possible that initially you will be in different places about it. Listen to one another and reflect the other's feelings back to them: for example, say, "I hear that you are worried about getting pregnant." At a minimum, you should address birth control, if you are considering having sex. Pregnancies can definitely happen from one unprotected act of sex--even when you try to stop in time. There are a lot of resources out there about birth control, or about forms of sexual intimacy that can't lead to pregnancy. But, always talk first to ensure you are both ready to take things to the next level.
