Go to bed with gigolos, initially in rotation (7)
I believe the answer is:
turning
'rotation' is the definition.
(thesaurus)
'go to bed with gigolos initially' is the wordplay.
'go to bed' becomes 'turn in' (synonyms).
'with' says to put letters next to each other.
'initially' suggests taking the first letters.
The first letter of 'gigolos' is 'g'.
'turnin'+'g'='TURNING'
'in' acts as a link.
(Other definitions for turning that I've seen before include "Changing allegiance" , "Rotating; junction" , "Deviation" , "Side road (from main road)" , "Rotating; going bad" .)
