Time for contraception? Strip (7)
I believe the answer is:
pillage
'strip' is the definition.
('pillage' can be a synonym of 'strip')
'time for contraception?' is the wordplay.
'time' becomes 'age' (age is a kind of time).
'for' says to put letters next to each other (I've seen this in other clues).
'contraception?' becomes 'pill' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'age' put after 'pill' is 'PILLAGE'.
(Other definitions for pillage that I've seen before include "Rob with violence" , "Plunder, sack" , "Violent stealing" , "Loot" , "Sacking" .)
