I slump awkwardly, embraced by man, irresistible (10)

I believe the answer is:

compulsive

'irresistible' is the definition.
(thesaurus)

'i slump awkwardly embraced by man' is the wordplay.
'awkwardly' is an anagram indicator.
'embraced by' is an insertion indicator.
'man' becomes 'cove' (old-fashioned term for a man).
'i'+'slump'='islump'
'islump' anagrammed gives 'mpulsi'.
'mpulsi' placed within 'cove' is 'COMPULSIVE'.

I've seen this clue in The Times.
