Girls don't usually learn to masturbate until they're toddlers, potty training seems is the most common time, meanwhile boys usually figure out pulling on their handle feels good as an infant. Parents then spend the next several years telling them to get their hands out of their pants &/or contemplating whether or not duct tape on their diaper constitutes a bad idea or not. Feeling good & sexual, though, are 2 different things. Even an orgasm -much less just playing with myself- was no different than ice cream, or jumping off a swing, doing a wicked cool trick on my bike, swinging around a bar, jumping into a cold pool on a hot day, or a Christmas present ...all fun things... until I hit puberty. The only thing that made it any different was the taboo nature of it.
If you're interested, sex & sexuality research has come a looooooong way from the Kinseys, and even the original Ks were pretty phenom / groundbreaking. But modern research also includes differences in culture, generation gap, normal childhood exploration vs abuse, and a whole lot of other modifiers. Any intro to sex & sexuality textbook can give you heaps of info / actual stats & numbers / tons of really solid research & trends.
Still, unless you've taken that class in college -or had kids- a whole lot of people tend to think that any kind of "sexual" act -or even thought- by kids younger than puberty = sexual abuse history. It doesn't. There may be, but the vast majority of people haven't been sexually abused.
This isn't to say you weren't.
However, purely going off of interest/awareness/masturbation at an -unspecified- young age? The odds -purely by numbers/probability- are in favor of "normal childhood exploration / experimentation".
