An Irish university is playing a key role in one of the largest sex surveys ever to be carried out.
Researchers at the National University of Ireland (NUI) Galway are taking the lead on a study that will ask tens of thousands of adults around the world about their sex lives.
The International Sex Survey, which can be completed by anyone aged over 18, will try to uncover different sexual behaviours, preferences and motivations linked to the sex lives of adults.
