But it inspired Hannah to share her own story, writing: "I've been waiting to tell my story. #stubblesurivor".
While Hannah didn't explain exactly what happened, the comments section blew up, many speculating she caught a staph infection during her romantic encounter.
These infections are caused by a bacteria called staphylococcus which lives on the skin naturally.
However if the bacteria enters the bloodstream through a wound, such as scratches caused by stubble, it can cause sepsis, skin infections and boil-like sores, Healthline states.
Many were horrified by Hannah's experience, suggesting her partner might have had poor hygiene, passing the bacteria into the broken skin on her chin caused by his stubble.
"Methinks there was something filthy on his beard," one wrote.
"I hope you never kissed that dirty dude again," another asked.
While one woman claimed: "Beards are literally dirtier than toilet seats if not cleaned properly."
Others were confused, with many stating their experiences with beards and stubble had never resulted in the same ordeal Hannah had endured.
"My husband has had a beard the entire time I've known him and this has never happened to me," one shocked woman explained.
"Can someone please tell me how this happened? I love making out with stubbly men," another asked.
Many thought it was funny, making jokes about being grateful to kiss women rather than men.
"Thank god I'm dating a girl," one person remarked.
