I'm a male prayer leader (4)
I believe the answer is:
imam
'prayer leader' is the definition.
(I've seen this before)
'i'm a male' is the wordplay.
'a male' becomes 'am' (I've seen this in other clues).
'im'+'am'='IMAM'
(Other definitions for imam that I've seen before include "Muslim religious leader" , "Ma, I'm off to find religious Muslim" , "Man who leads prayers in a mosque" , "Islamic religious leader" , "Mosque's prayer leader" .)
