Fair fucks to women. They keep periods so well hidden you wouldn't even know they had them if you didn't know any better.
If men had periods, there would be used fanny pads absolutely everywhere.
You'd be in school and someone would go "PussyinBoots - cm'ere I want ya" you'd go over and some scumbag would rip out their jam-rag and shove it right into your face lol.
"take that Pussy ya faggit!"
