"Like a Virgin" followed on the radio (6)
I believe the answer is:
chaste
'like a virgin' is the definition.
'followed on the radio' is the wordplay.
'followed' becomes 'chased' (I've seen this before).
'on the radio' shows a homophone (sound like).
'chased' sounds like 'CHASTE'.
(Other definitions for chaste that I've seen before include "Modest, pure" , "without excessive ornamentation" , "pure and simple" , "Restrained, modest" , "Maidenly" .)
