'turned on right? in corner' is the definition.
'nook' can be an answer for 'corner' (synonyms). I'm unsure of the 'turned on right? in' bit.

'endless sex' is the wordplay.
'endless' means to remove the last letter.
'sex' becomes 'nooky' (informal term for sex).
'nooky' with its last letter taken away is 'NOOK'.
