There are different ways of being tough. I remember once reading some doctor who'd been involved in some construction project, in the Brazilian rainforest, I think.

He said that the difference between giving some painful injection to the indigenous workers, and to the workers from outside places, such as
North America or Europe, was that the locals would roar out with pain while holding the hand being treated rock steady, and the Westerners would screw up their faces and bite their lips and not utter a sound, and their hands would wobble all over the place. It was much easier getting the needle in the right place with the locals.

In both cases they'd have been male in this case. I have a feeling, though, you might get some analogous difference between the way men and women act in that kind of situation.
