Does every girl masturbate?
Some women do. Some don't even understand why someone would do it. To them masturbation is pointless.
Almost every guy does masturbate, and those that say they don't, are lying.
Guys produce sperm constantly. The sperm has to "leave the building" so to speak, so if the guy doesn't do it through sex or masturbation, nature will do it during the night with a wet dream - called Nocturnal Emissions (great name for a rock band, by the way).
and every makle doesnt masterbate either
while a fair majority of the population do it, not everyone does
somepeople dont do it for religiouse reasons, other people have no intrest at all in masterbation or sex, some didnt think of trying it or dont want to, ect
there are many reasons who both males and females either choose to not masterbate or choose when they want to start
Nor does every guy
Some people say they dont when they do, because they dont want to admit it, some genuinely have never masturbated.
I highly doubt it.
No not all.
