Would you have promised your father you'd stay a virgin until marriage? That's the subject of photographer David Magnusson's project Purity, in which he's captured teenage girls with their dads after they've pledged abstinence until they're officially a Mrs.
However, Magnusson claims - following this project - he understands why fathers and daughters would go through the process of making these promises.
Talking to Refinery29, he says: "When I first heard about the purity balls, I imagined angry American fathers terrified of anything that might hurt their daughters or their honour.
And here's us thinking rapists lead to rape.
The connotations and message of the practice seems to be good girls are virgins and bad girls are shagging.
And, before you ask, no, sons aren't promising their mothers they'll keep it in their pants until they've found a wife.
The worst thing about the practice is it takes something private and sensitive and makes it public. Surely losing your virginity is one of the most personal experiences and choices a girl can have?
What do you think - if it was widely practiced in the UK, would you have made a purity pledge to your father? Tweet us @MyDailyUK.
