Curious: At which age do girls start to masturbate?

I did not asked men, because I know the answer. I personally started to try to clear myself hard and rub at age of 11. Of course did not know much what to do, but this is how I started. Heard friends talking just about masturbating, but was ashame to ask. First solution drops came little then. First orgasm discovered much more later. How roughly you? Never spoke to wide audience of girls around this before and I am curious for your answers. It really is different for every girl. A lot of girls as expected as you know claim they don't do it at all. I one-sidedly started around age 12, Some girls earlier than that, some girls then than that. Especially since its so wide range as to when a girl can hit puberty/get her period, its also a short time ago as wide range as to when their hormones start kicking in.
Obviously, I be curious when I was younger on how sex would get the impression.. so around 11-12 I did masturbate, but I decided I didn't want to do it anymore, as.. resourcefully, I don't remember.
