'Between The Sheets', perhaps naughty bits put together (8)
I believe the answer is:
cocktail
'between the sheets perhaps naughty bits' is the definition.
I can't tell whether this defines the answer.
'put together' is the wordplay.
'put' becomes 'cock' (cocking is a kind of putting).
'together' becomes 'tail' (I can't justify this - if you can you should give a lot more credence to this answer).
'cock'+'tail'='COCKTAIL'
Can you help me to learn more?
(Other definitions for cocktail that I've seen before include "Manhattan, for example" , "Screwdriver, for instance" , "dish with prawn" , "Mixed alcoholic drink or prawn appetiser" , "Possibly old-fashioned" .)
