God of sex raised whip (5)
I believe the answer is:
titan
'god' is the definition.
(Titan is an example)
'sex raised whip' is the wordplay.
'sex' becomes 'it' (a common euphemism).
'raised' says the letters should be written backwards.
'whip' becomes 'tan' (I can't explain this - if you can you should believe this answer much more).
'it' written backwards gives 'ti'.
'ti'+'tan'='TITAN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for titan that I've seen before include "Giant of Greek mythology" , "Giant -- rocket" , "Person of great size" , "Taint in a great man" , "bigwig" .)
