One often sleeping unleashed extremely masculine odours (8)
I believe the answer is:
dormouse
'one often sleeping' is the definition.
I can't tell whether this definition defines the answer.
'unleashed extremely masculine odours' is the wordplay.
'unleashed' indicates an anagram (letters are unleashed from their original order).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'masculine' with its middle removed is 'me'.
'me'+'odours'='meodours'
'meodours' with letters rearranged gives 'DORMOUSE'.
Can you help me to learn more?
(Other definitions for dormouse that I've seen before include "Partygoer" , "Small British rodent" , "Small rodent that hibernates in winter" , "Creature in teapot (Alice)" , "Wonderland creature" .)
