Excuses arising from training in kinky sex with me (7)
I believe the answer is:
exempts
'excuses' is the definition.
(to exempt is to excuse from)
'training in kinky sex with me' is the wordplay.
'training' becomes 'pt' (Physical Training).
'in' is an insertion indicator.
'kinky' indicates an anagram.
'with' says to put letters next to each other.
'sex' put after 'me' is 'mesex'.
'mesex' anagrammed gives 'exems'.
'pt' put inside 'exems' is 'EXEMPTS'.
'arising from' acts as a link.
(Other definitions for exempts that I've seen before include "Grants immunity to" , "Frees from obligation, say jury service" , "Lets off" , "Frees from liability" , "Excuses" .)
