The couple were reportedly at the beach near Porto San Giorgio in Italy when they got amorous. Reports say "suction" led to them getting stuck together, leading to a trip to a nearby hospital.
This is what happens when you google it.
However experts have told i100 the details of the story are very unlikely to be accurate. Professor Helen Ward, an expert in Public Health from Imperial College London told i100 "I wouldn't say it's impossible, nothing's impossible, but I think it sounds highly unlikely."
She said that if two people did get stuck together briefly, the man would likely manage to release himself by losing his erection.
Separately a spokesperson for Brook told i100: "It does actually have a medical term 'penis captivus', if you will. From what we gather it is exceptionally rare, but it can happen (but not necessarily because of water or ‘suction’ though), and is something that occurs more frequently in animals than humans. Research suggests that, for most couples, if this happened it would last a matter of seconds, so it would be incredibly rare for a couple to require medical help."
