Extraordinary time with adults getting stirred up (10)
I believe the answer is:
stimulated
'stirred up' is the definition.
(synonyms)
'extraordinary time with adults' is the wordplay.
'extraordinary' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'time' put after 'adults' is 'adultstime'.
'adultstime' anagrammed gives 'STIMULATED'.
'getting' acts as a link.
(Other definitions for stimulated that I've seen before include "Energised" , "Provoked the senses" , "Created excitement" , "Aroused" .)
