Thank you for your thoughts, Dr. Handsfield. I appreciate your answer as well as the information I've gleaned from your past posts these past couple days. Much of this information is new to me.
As you might have suspected, the ER doctor who prescribed me the PEP was hesitant to do so. But because I was in a panic and agreed to make an appointment with an HIV specialist, he complied with my request. He did not consider Korean immigrants or CSW's to be a high risk group, but thought I should confirm his assessment with a specialist.
In regards to the PEP prescription, I have an appointment with an HIV specialist to see if I should continue per the ER doctor's request.
Thank you again for your perspective.
Best,

Welcome to the HIV forum. Your question is like many others and the replies are the same.
First, heterosexually transmitted HIV is extremely rare after single sexual exposures. Most HIV transmissions occur in couples who have repeated sex for many years, typically with the infected person being unaware s/he has HIV.
Second, it is unlikely your partner had HIV -- and especially unlikely given what she said after you called her up. Most people don't lie about it when asked directly. Her "cavalier" attitude should be reassuring, not a cause for worry.
Third, even if she had HIV, the average chance of female to male HIV transmission for unprotected vaginal sex is once for every 2,000 exposures. That's equivalent to having sex with HIV infected women once daily for 5 years and maybe never catching it. HIV is not all that easy to transmit!
I'm surprised you were prescribed PEP. I would not it for you, even if you asked for it. However, perhaps there are local data that support a more aggressive approach in this particular community. For example, if it were known that CSWs in the area -- or mabye Korean immigrants in particular -- have particularly high HIV rates, perhaps PEP is warranted. But I am doubtful.
Now to your specific questions:
1) See above. As I recall, HIV rates are low in Korea -- like in Japan, where they are very low.
2) This sort of exposure does not fit into usual criteria for PEP.
3) Have an HIV antibody test in 6-8 weeks. You can expect it to be negative.
4) I'm not going to go against the advice from the doctor who prescribed PEP. If your partner has a negative HIV test, please talk to the doc about continuing or stopping PEP. My recommendation would be you don't need it in that case, but this should be between you and the doc who prescribed it.
Bottom line: There is little if any HIV risk here. But discuss continuing PEP with the doc who prescribed it.
