Your gesture conceals desires (5)
I believe the answer is:
urges
'desires' is the definition.
'your gesture conceals' is the wordplay.
'conceals' indicates the answer is hidden within the clue.
'URGES' is hidden within 'your gesture'.
(Other definitions for urges that I've seen before include "Advocates strongly" , "Persuades to do something" , "Strong impulses" , "Presses to do something" , "Inner promptings" .)
