A little heterosexual love personified (4)
I believe the answer is:
eros
'love personified' is the definition.
(I've seen this in another clue)
'a little heterosexual' is the wordplay.
'a little' indicates the answer is hidden within the clue (a little bit of the clue).
'EROS' is hidden within 'heterosexual'.
(Other definitions for eros that I've seen before include "Winged archer" , "In Greek myth, the god of love" , "asteroid four hundred and thirty three" , "Greek name of Cupid" , "Name given to statue" .)
