I ll try to be brief, so here is the story. I had an interaction with a Brazilian sex worker (escort) in
London. The interaction consisted of deep kissing, fingering, and protected vaginal sex. The part that worried me the most was the un-protected oral sex which she performed on me. The following days were very stressful.
Two to three weeks after intercourse I experienced a sore throat/blocked nose/cough, mostly typical of a cold.
