5 Months ago I received oral sex from a prostitute and a rimjob. No vaginal intercourse. The rimming was for 5 minutes and oral for a couple of minutes. A month or so in I noticed some discomfort in my armpits that lasted a couple of months on and off. A couple weeks I had sever flu/cold symptoms....fever, coughing, runny nose, etc and have had a persistent white tongue for the last week and a half or so along with a cough. What are my chances this could be related to HIV or another STD? Should I get tested? I am becoming increasingly worried.
