In ancient Greece, women entertained themselves with the olisbos (meaning "to insert").
It was an artificial phallus measuring around 15 centimeters. There were different types, but the least expensive was the olisbokollix, a bread dough dildo resembling a breadstick: a DIY and custom-made option.
It was also common to use olive oil as a lubricant.
So back on the day, they didn't have sex shops, they had bakeries. And that folks is the origin story of Yeast infection.
