To be honest, many of us were exactly like you when we were 13, too. The reality is that masturbation is a totally new feeling for you (assuming that you have started up within the last year or so), and of course with all the hormones within you masturbating is going to be something you are going to want to do. As long as masturbating is not something that impedes your normal routines, then you are good. Based upon what you describe above you seem fine to me, for what that is worth.
