Have you been able to limit how many times a day you masturbate? Although it feels good I don't think masturbating as frequently as you do is good for you. You might over do it and end up with a painful vagina. I'd suggest slowly decreasing how many times you masturbate a day. I would assume your sex drive is kind of normal for your age; It might also decrease as you get older. Do you also masturbate 4 to 5 times on a school day, or is it only when you have a day off? See what others have to say about this b/c I could be totally wrong, but that's my answer.
its normal to feel so ur growing up but cut down on masturbating u might hurt ur self
From one female to another, this is absolutely normal. Don't cut down unless you're in pain. Do it as frequently as you like and don't worry! If it interferes with your ability to live your life, go to the doctor and get your hormone levels checked. But other women have this level of libido, and it isn't all that abnormal.
As long as it doesn't harm you or interferes with your daily life (Like you come late or you start canceling your friends JUST because of it) it shouldn't be a problem, it can even be very healthy for your mental health since it makes you feel good and distracts you from negative thoughts.
