Study arousing the body by mutual agreement (10)
I believe the answer is:
consensual
'the body by mutual agreement' is the definition.
I can't tell whether this defines the answer.
'study arousing' is the wordplay.
'study' becomes 'con' (con can informally mean to study).
'arousing' becomes 'sensual' (I can't justify this - if you can you should believe this answer much more).
'con'+'sensual'='CONSENSUAL'
Can you help me to learn more?
(Other definitions for consensual that I've seen before include "No such decision imposed" , "Involving free agreement" .)
