Hi, I am a 36 year old guy. 8 weeks ago I had unprotected vaginal sex and ejaculated inside a 21 year old British Pakistani escort. After 15 days I got a headache (1day), with a bitter taste in mouth (present). I did not present with a fever, sore throat, rash etc... I tested negative at 6 weeks (41 days) with a 3rd generation Insti test (Finger prick) and 4th generation combo test (Venous). I was told the test is 96-99% accurate between 4-6 weeks and 8 weeks is considered conclusive by UK guidelines. 1) Was my risk high, considering I had a natural 65% protection through circumcision from birth? 2) Are the symptoms described related to ARS? can they persist for 8 weeks? 3) Is my negative 6 weeks result likely to change?
