Perhaps a Séamas-an-bhuid or Lusty Man ?
  
The strange Irish gate-pillar figure holding a key, which 
  is
  perhaps as much as five centuries later than the Romanesque exhibitionist carvings. 
  
Compare this figure with...
  ...another remarkable key-bearer at Broadford, county Clare, sawn off at 
  the waist...

and so possibly exhibitionist also before it was mutilated.
Compare both figures with a key-carrying figure on a Mithraic altar from SW France.
  Compare the Ballycloghduff Lusty Man with the male on the Romanesque 
  doorway at Saint-Front-sur-Nizonne in France.
