All the girls I dated curse either somewhat more than me, or far more much than me.
I will admit I do not curse much (I prefer to make statements of impact, even when mad, and often curses become so common they lose that.
) and many girls I have dated have from from, well far Canadian Eastern communities...
But in my experience I have heard girls curse as often if not MORE then men. They just do it more casually so it slips by. Not surprised at all.
Really, people are people.
