There is no signficant risk here. I'm wondering why you are so focused on those particular infections at all. Despite what you have apparently read, the hepatitis C virus (HCV) is not sexually transmitted at all, except occasionally among men who have

It is wise for all people to be vaccinated against HBV, and it is a higher priority for those who are sexually active outside permanent, mutually monogamous relationships. But no STD expert would recommend that someone be tested for HBV or HCV after a single exposure like you descirbe.
