I am a married man and did a stupid thing. 4 days ago I performed oral sex on an exotic dancer. She said she came to climax so I assume I injested her vaginal secretions. About 2 days after the act, I started feeling discomfort in the neck and assumed it was my lymph nodes. I have had a queezy stomache and what feels like a low grade fever although the thermometer did not register a fever. Basically, I am freaking out that I caught something and wondering if I should get tested. I have no sore throat and the "warm" sensation does not persist although the neck discomfort has remained. Please let me know if you think I am overreacting and more likely have a flu or if I should get tested for HIV, or other std's. Thank you.
