A man who will easily put out boss (4)
I believe the answer is:
stud
This clue might be a double definition.
'a man who will easily put out' is the first definition.
'stud' can be an answer for 'a man' (stud is a kind of man). I am unsure of the remainder of the definition.
'boss' is the second definition.
(both can mean a metal decoration)
Can you help me to learn more?
(Other definitions for stud that I've seen before include "Large-headed piece of metal - horse-breeding establishment" , "Place of breeding" , "collection of cars" , "upright" , "Macho - stables - boss" .)
