I don't regularly go out to pull, and in fact in a ratio its probably very slim compared to the amount of times I go out with no intention of pulling, but from time to time yes, girls do go out simply to pull. Women have needs just as much as men.
And if I am hell-bent on pulling(as in, I can't be bothered giving come hither stares all night) then I just approach a guy, some as guys do with girls.
