Sin and sex repressed by Conservative jurisdiction (9)

Ross

I believe the answer is:

territory

I'm a little stuck... Click here to teach me more about this clue!

'jurisdiction' is the definition.
(thesaurus)

'sin and sex repressed by conservative' is the wordplay.
I cannot really see how this works, but
'sin' could be 'err' (to sin is to err morally) and 'err' is located in the answer.
'sex' could be 'it' (a common euphemism) and 'it' is found in the answer.
'conservative' could be 'tory' (informal term for a Conservative Party member) and 'tory' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for territory that I've seen before include "ground" , "Geographical region" , "Tract of land" , "Region marked off for some purpose" , "Political land mass" .)
