Transmission of HCV is much more difficult that you must imagine. It really
does appear to require blood-to-blood contact - nobody I know of or have read
about believes they contracted it through any other route. Not one monogamous
couple with one HCV+ partner I know or have read about has infected their
spouse through years - decades even - of sexual contact.

Testing for HCV antibodies is fairly cheap and quick, so if only for your own
reassurance, getting tested might be worth it. Otherwise, unless you can
identify some possible blood-to-blood contact - shared needles, shared razors
or toothbrushes, etc - you really don't have much reason to be concerned.
