Even a broken clock, as they say… Our natural human functions should not be shamed. Especially not the ones we need for the species to survive! (At this point I’m not even sure if that’s desirable given what we’re doing to each other and the planet). If you are a man who thinks period products are gross, please grow up. And for the girls and women, I hope we can be more open about our periods. They’re annoying (I know!), but they’re nothing to be ashamed of. #period #menstruation #feminism #femi
