I've been serious with this guy that I've known since kindergarten for a little more than half a year now. He makes me really happy and I love him. And lately we've been discussing sex. It would be my first and his first**. We both have those feelings about each other but we don't know if it's appropriate at our age. He said he isn't going to pressure me into it, but some days I'm think I'm ready and others I'm scared. Any advice?
