Current male desire (4)
I believe the answer is:
ache
'desire' is the definition.
(ache can mean a passionate desire for something)
'current male' is the wordplay.
'current' becomes 'ac' (alternating current).
'male' becomes 'he' (he refers to a man).
'ac'+'he'='ACHE'
(Other definitions for ache that I've seen before include "Play up" , "A dull lingering pain" , "Dull continuous pain" , "Shakespearean character" , "Dull prolonged pain" .)
