All this masterbation... is it normal to masterbate everyday?

It seems like every day I catch myself dying to get somewhere private and alone so I can masterbate and finger myself… I have like 2 vibrators but you can hear the buzzing of them and I usually just like using my fingers. I dont finger myself that much I just rub my clit till I get an orgasm.
yesterday I don’t know what was going on but I was on one couch and my sister was on the one right next to me and I had such a bad urge to start rubbing my clit I started to play down tehre a little bit under a blanket right in front of my sister.. she didnt notice what I was doing but still. Then I usually only masterbate about once a day but yesterday I did about 3 or 4 times. And then this morning I did before I went to school and then when I came home from school and I probably will again tonight. But last night when I was doing it before I went to bed I didnt get an orgasm wihch is unusual for me… why didnt I get an orgasm??? and is it unusual I want to masterbate this much?? and what can I do to cut back??? can you please answer quickly because I really want to know whats going on… THANK YOU!
