Woman has sex with affairs (8)

I believe the answer is:

shebangs

'affairs' is the definition.
(shebang can mean a particular affair or matter)

'woman has sex with' is the wordplay.
'woman' becomes 'she'.
'has sex with' becomes 'bangs' (bang can informally mean to sleep with).
'she'+'bangs'='SHEBANGS'

(Another definition for shebangs that I've seen is " matters".)

I've seen this clue in The Guardian.
