I am a female, of age 18. 3 weeks ago i came in contact with a guy i thought i knew, never crossed my mind that i should ask about his status but at the time i recently got my tongue pierced, he pressured me to give him oral and i did, now im worried that i may have HIV, I've been coughing, stuffy nose, headache, and congestion in my chest, its been a week and a half and i still have congestion, what are my chances of having HIV. Very scared since that was my first time.
