Pleasure-seeker (8)
I believe the answer is:
hedonist
'pleasure-seeker' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hedonist that I've seen before include "sybarite" , "A seeker after luxury" , "he puts pleasure before work" , "Extreme pleasure-seeker" , "Epicurean" .)
