would I see symtoms in one area and not the other
I had both unprotected Oral / sex
Well, if you had unprotected sex, you would be more likely to be having symptoms of an std in the genital area. Even if you had unprotected oral sex, it is not that common at all to get an std via oral sex. If you did not have oral sex, then the sore throat is not at all associated with an std.
unprotected sex puts you at risk, but you're being paranoid at this point.
only testing can tell you for sure.
