Is there such a thing as a FEMALE perverted character?

It seems that in every anime series that has a perverted character, said character is always a boy.

So far, the only perverted female I've seen is Kurumu Kurono (which is ironic, since she hates the perverted male of R+V, Gin Morioka).

I don't know about you, but I think a girl constantly pressing her boobs up against a guy's chest qualifies as perverted.
