That would be just no fun at all. Well, I'm going to tell you. First thing I would do is get the driving age changed to 18. I would also focus nearly completely on education. Teach the children well, and you won't need to worry about them later.
Abortion is a big one.
I don't like abortion. I do not think it should be used as birth control. If you think you are responsible enough to stick or get stuck, then you need to suffer the consequences. However, being a man, I have no right to tell any woman what to do. So, I would never outlaw abortion, just for the simple fact that it is not my place.
