WOW!!
It's not how many times WE want you to do it. Don't get all stressed over it and how many times you should do it. You do it as often as YOU feel like doing it. Masturbating isn't going to hurt you and there are no rules about how often to do it.
From your description, The only thing I can see that might cause you problems will be your overwhelming desire to CONTROL it. Did you really count how many times you did it over all those years? I can see that causing a psychological problem maybe. I never counted how many times I did it. When I was 11 I had a girl friend and for some stupid reason I thought I should stop doing it for her. That didn't work very well because thinking of her made me WANT to do it. All that idea about controlling it did for me was stress me out.
you can mastrubate how many times you want :)
