Is the F Word used too often in movies by women?

Swear words like F- and S- have become cliches since they are used so much.  In the past month I saw The Fighter and No Strings Attached where the F- word was used just too much by women.  The characters in The Fighter were blue collar and relatively uneducated and used the F- word as an expletive.  The women in No Strings Attached were physicians and used the word to describe the sex act.  I thought that in both films expletives were used too often.
