This is a really hard age because young males and females are often all legs and arms and shy. The best thing for him to do is ask her to a "good" movie and see if she will go with him. It's wise that after that he meet with her parents and no doubt her mother will call you. I've gone through this with my nephews. It will work out. Be sure you tell him that not all girls may want to go out with him, but some will. Rejection is simply part of life.
