It's hard to say.  I have yet to come across a real, live human other than myself that uses bitcoin.  I don't see the point in going to bitcoin meetups, and it simply is not common enough to see men and women buying coffee with it yet.  

So I can only go by what I see online.  And it's a giant sausagefest in the bitcointalk forums and on reddit.  I'd have to say no, there are no women who use bitcoin.
