I think that most girls and (younger) women in Germany do shave nowadays. But that was different not so many years ago.
(Female) German exchange students who go to the United States are urgently advised by their respective organisations to shave because Americans feel that unshaved arm pits and legs are really disgusting and would never understand such a barbaric behaviour.
The fact that it seems necessary to give this advise makes it clear that shaving is not such a matter of course in Germany (and maybe in other European countries too) as in the USA.
But the continous process of Americisation of world wide life styles will make the differences soon indistinguishable.
