Rogue wed Angolan clerk for sex (6,9)

I believe the answer is:

carnal knowledge

'sex' is the definition.
(carnal knowledge is a kind of sex)

'rogue wed angolan clerk' is the wordplay.
'rogue' indicates an anagram (letters go rogue).
'wed'+'angolan'+'clerk'='wedangolanclerk'
'wedangolanclerk' anagrammed gives 'CARNAL KNOWLEDGE'.

'for' is the link.

(Another definition for carnal knowledge that I've seen is " It".)

I've seen this clue in The Independent.
