I met a guy 4 weeks ago. We engaged in fingering and frotting, no oral sex and Im sure no penetration had happend, I thought of taking pep but I was told no penetration = no risk. However on the 3rd week I developed symptoms like runny nose, mild fever (37.3°c), wet cough and chills. I made a rapid ab/ag on the first day the days appeared and it was negative. Should I repeat the test? Was I really not in a risk?
