We are naked, writhing, aroused again (10)
I believe the answer is:
reawakened
'aroused again' is the definition.
('awakened' can be a synonym for 'aroused' so perhaps 'reawakened' is OK for 'aroused again')
'we are naked writhing' is the wordplay.
'writhing' indicates anagramming the letters.
'we'+'are'+'naked'='wearenaked'
'wearenaked' anagrammed gives 'REAWAKENED'.
(Other definitions for reawakened that I've seen before include "Roused again" , "stirred up afresh" , "Revived" .)
