I am an American man, about 14 months ago I gave an American woman (of unknown STI status) unprotected cunnilingus. I likely had bleeding gums
at the time, but cannot remember for sure.
Roughly 36 hours after the encounter, I came down with pretty rough cold/flu like symptoms (fever, sore throat, runny nose, etc.) This lasted about a week and a half and around that time I also developed a light, reddish, slightly itchy rash on my buttocks and upper legs.
