You had brief, condom protected
sex and briefer still receipt of unprotected oral
sex- neither activity is a risk factor for HIV. You can find comments to the contrary on the internet or on other sites where commentators do not want to take a "chance" in being wrong but the facts are that there is no evidence of HIV being spread through oral sex.
I see no need for testing.
As for your sore throat, I suspect this is coincidence, and nothing more.
