Yes
yeah girls are suppose to have a better center of gravity which increases balance. First you got to find that balance by practicing standing on one foot like a flamingo. A regular stance on a skateboard is left foot forward while the right foot pushes, but some people have different stances like mongo, goofy, and goofy mongo.
Yeah girls can skateboard!! I myself wouldn't do it though because I'm a really clumsy person. If you want to skateboard then you should be able to do that. It doesn't matter whether your a guy or a girl, just do it.
if practice why not :)
