On the night of the 6th of March, I performed unprotected cunnilingus on a female sex worker in UK. She was of Spanish origin. It lasted a few minutes. There was no other sexual activity. The following day I developed a sore throat and had flu like symptoms. 3 days later I developed a blister on my upper inner lip. I thought it might be HSV-2 related from the oral and bought acyclovir cream. As far as I can recall I have never suffered a cold sore before. I am generally in good health and in terms of oral hygiene I sometimes experience minimal bleeding post brushing my teeth. I do not recall any gum bleeding that night.
It has now been 13 days post exposure . My flu like symptoms settled few days ago but I woke up today with a slight throat irritation. Also sometimes My upper arms feel achy and itchy and I don't know if it is just anxiety but I begin to notice some redness at my upper arms and a folliculitus type rash, but I think this has been chronic . I did a chlamydia / gonn throat swab 1 week post exposure and it came back negative. I checked a Full blood count 1 week post exposure and it was normal. The blister on my inner upper lip, although smaller, persists. It doesn't look like a herpes lesion from Internet images and I was wondering if it may be a mucocele.
I know you guys have answered similar questions , but for my own peace of mind, I am concerned about my risks of HIV from the cunnilingus or any other STIs. I would be grateful for your advise on my symptoms and what tests if any I should have. I have a partner and have not been near her for 2 weeks now in fear of passing anything on. Also in terms of a theoretical risk of HIV from cunnilingus , what quantity of vaginal fluid or menstraul blood is considered significant risk?
