^ Yeah, that's what I was thinking. It's like weight lifting. Smaller weights = higher reps!
Is this a serious question? I don't think there is any way it could. In fact, it could probably help your muscular development.
However, over masturbation might hurt you later in your sex life (if it hasn't begun yet). Often times super-masturbaters have problems producing semen when the "time comes". Other things they face are weak erections, and loss in sexual interest.
So, don't whack it too much!
