There are a couple of good websites that explain this issue.
The best one I can find at the moment is:

But to answer your question in short sentence: Yes. It is "normal" if you define the word "normal" to mean the "majority" of people. It is true that most people do it, including boys and girls. About 50% of people masturbate for the first time before puberty, while the other 50% begin masturbating during the onset of puberty. Adults also masturbate. This includes men and women who are older, married people, people who have children, and even lots of people who are "mature"; that is: They are older (retirement age).
It is true that boys and men masturbate more often than women, and men also admit to masturbating more often than women. However, the majority of girls and women do it too.
