Did you kiss her?
If you didn't kiss her, I can't see any real risk for oral herpes. Do you have mouth sores?
There are any number of things that could have caused your illness - the flu, strep, about a dozen different upper respiratory viruses, and I wonder if you got tested for anything other than STIs, besides Covid? Did your doctor do a throat culture?
You could have easily caught a virus at the grocery store as you could have from the stripper - one that isn't sexually transmitted.
In any case, if you had been tested for herpes now, it would have been way too soon to know if you had it from the stripper. If you tested positive, it would have been a pre-existing infection, not a new one.
