May be even true of sex (8)

I believe the answer is:

venereal

'sex' is the definition.
(thesaurus)

'may be even true' is the wordplay.
'may be' indicates anagramming the letters.
'true' becomes 'real' ('real' can be similar in meaning to 'true').
'even' is an anagram of 'vene'.
'vene'+'real'='VENEREAL'

'of' is the link.

(Another definition for venereal that I've seen is " Of disease or infection from sexual promiscuity".)

I've seen this clue in The Guardian.
