Bold move to curb two individuals' sex drive (6)
I believe the answer is:
libido
'sex drive' is the definition.
(I've seen this before)
'bold move to curb two individuals'' is the wordplay.
I cannot quite understand how this works, but
'bold' could be 'b' (abbreviation) and 'b' is found within the answer.
'move' could be 'do' (doing is a kind of moving) and 'do' is found in the answer.
'two' could be 'ii' (Roman numerals) and 'ii' is found in the leftover letters.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for libido that I've seen before include "Psychic, sexual, energy" , "Emotional craving" , "Instinctive desire" , "I'd boil over with sexual energy" , "Sexual or psychological urge" .)
