the girls at my school have to word their period cramps as 'stomach pain', otherwise they cant lay down in the nurse/get sent home because 'cramps arent a reason to miss class!'
the ONLY difference is that we are womyn. all the sudden our pain isnt real pain, just because men cant relate to this. the second our pain stems from us being female, we cant take a break because these establishments see female pain as secondary to male pain.
i could be having debilitating cramps, but a boy with a stomachache would be prioritized over me because womyn are expected to just take their pain as the normal to not disturb men.
