pederosis

noun

1. (rare, uncountable)sexual impulse directed towards children; paedophilia

   “I knew exactly what I wanted to do, and how to do it, without impinging on a child's chastity; after all, I had had some experience in my life of pederosis; had visually possessed dappled nymphets in parks; had wedged my wary and bestial way into the hottest, most crowded corner of a city bus full of strap-hanging school children.”
