HIV risk analysis

[Concerned_frightened]

Firstly, since this text-box is allowing a very limited amount of characters, due to the complex nature of my concern I will have to break down my case with as many words as I can fit here, proceeded by the remainder in the comment section.

Background:

Dear Dr. Hook,
I am a student who was raised in a well-off, loving upbringing, who foolishly experimented with the services of a sex worker for the first and only time exactly one month ago. The day before the booking I was shaving my genital region but in doing so, accidently cut my testicles (to the point of bleeding). Irrespective of this, the next day I arrived to a much more run-down apartment than I envisioned only to be greeted by a more elderly and rough looking woman than what was advertised in the pictures online. At that point I should’ve had the common sense to turn around and leave, but thoughtlessly I handed her the money and continued. I requested condom protected fellatio in order to mitigate HIV/STI/HCV risk and she obliged. As soon as this started I visibly observed lots of her saliva quickly drip down the condom and onto the area of the cut suffered the day before, but to my horror the saliva was completely opaque, creamy and white. Adding to this, she was strangely and noticeably grimacing while avoiding using her lips and with a wide-open mouth motion she was using solely her throat to gag up and down. I can only rationalize that she must have been doing this to avoid painful oral lesions on her mucous membrane. This was very unnerving and after I ejaculated, I felt disturbed and anxious to leave.

Dr. Hook and I take questions randomly, without regard to requests for one of us or the other.  Our opinions and advice never are significantly different from one another, even if our styles are variable.  I'll be handling your question.  

The reason for the 2,000 character limit (about 400 words) is to require that the entire question be limited to the initial text box.  The moderators have neither the time nor inclination to read such long essays, and I have never seen a question that could not easily be condensed to the required limit.  Please condense your question accordingly, post it in a new follow-up comment below, and then I will respond.

Thanks--  HHH, MD
