Sexually attractive male boss (4)
I believe the answer is:
stud
This might be a double definition.
'sexually attractive male' is the first definition.
'stud' can be an answer for 'male' (stud is a kind of male). I'm not sure about the 'sexually attractive' bit.
'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 "Football boot's peg-like projection" , "Stallion for breeding - fastener" , "Playboy" , "Dot" , "gambling with cards" .)
