Straight there, after travelling round (6)
I believe the answer is:
hetero
'straight' is the definition.
(short for heterosexual)
'there after travelling round' is the wordplay.
'after travelling' indicates anagramming the letters (back).
'round' becomes 'o' (round can mean a round object).
'there' anagrammed gives 'heter'.
'heter'+'o'='HETERO'
(Other definitions for hetero that I've seen before include "Prefix signifying other" , "Straight (abbr)" , "Person attracted to the opposite sex (abbr)" .)
