Thanks for posting your query.
Oral is a part of regular sexual act.
It is good to clean your private parts well before oral act.
You would be having sore throat
that is infection of pharynx, which would be due to bacterial infection contracted by oral.
But it would also be due to a fish bone impaction
So, try with salt water gargles with warm water many times a day and also drink more warm fluids like water, milk, soupe.
You can also start a course of antibiotic of penicillin or macrolide
If the symptoms do not subside consult a physician.
Hope I have answered your query.
Wishing you good health.
