Hi 

Welcome to the Forum and thanks for your question.  This was a low risk encounter with little risk for acquisition of any STI.  Most lap dancers and commercial sex workers do not have STIs and cunnilingus is amongst the most inefficient routes of STI exposure, very rarely leading to infection if a partner happens to be infected.  Further, oral STIs typically are asymptomatic and when symptoms occur, increased phlegm and congestion would be unusual.  Finally, in the unlikely event that an infection was acquired and became symptomatic, symptoms would most typically take 3-4 days to occur.  I would not worry about this possible exposure and see no medical need for testing of any sort.---
