Welcome to the forum.
HIV is never been known to be transmitted by cunnilingus; and in general, oral exposure is risk free for HIV. So you are at little or no risk of HIV from the events described. In addition, your sore throat began too soon; ARS symptoms rarely start as soon as 7 days; usually it's 10-20 days. And sore throat, without fever, is almost never due to HIV. I'm sure you just caught a cold, unrelated to the sexual exposures you have described.
Based on the information provided, there is no need for you to have an HIV test, and you can safely continue unprotected sex with your wife.
I hope this has helped. Best wishes-- HHH, MD
