Charged with sex game (2,3,2)
I believe the answer is:
up for it
'game' is the definition.
(I've seen this before)
'charged with sex' is the wordplay.
I cannot quite understand how this works, but
'sex' could be 'it' (a common euphemism) and 'it' is found within the answer.
The remaining letters 'upfor' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for up for it that I've seen before include "Ready to take part" , "Game" , "Enthusiastic" .)
