The sexual exposure you mention was no risk at all for HIV. The virus has never been scientifically proved to be transmitted mouth to penis. If that occurs, it is extremely rare. Based on how people believe they were infected with HIV -- which often is mistaken -- CDC has estimated a risk of one chance in 20,000, if the oral partner has HIV. That is equivalent to receiving BJs by infected partners once daily for 55 years before transmission might be likely. In addition, it is very unlikely your "call girl" partner had HIV. Even among the most sexually active female sex workers, in most geographic areas under 1% have HIV. So combining both the low chance your partner has HIV and the extreme rarity it would be transmitted by oral sex, there is no chance you are infected yourself.

The skin rash of HIV is body wide, not involving only a leg or other localized site; occurs only with other symptoms of ARS, i.e. acute HIV infection (sore throat, fever, enlarged lymph nodes) 1-2 weeks after catching the virus, and then clears up. Recurrent rash for a year cannot possibly be caused by HIV -- it does not come and go.

For those reasons, you can be sure you do not have HIV. If you continue to worry about it, however, you could have a blood test for HIV. This does not mean I believe there is any chance you have it -- but some worried persons are more reassured by negative test results than by professional advice, no matter how expert. If you decide to be tested, you can be sure of a negative result.

I hope these comments are helpful and have stopped your worry about it. Let me know if anything isn't clear.

If you remain worried about it, have an HIV test. But there is no point in further discussion otherwise. There is nothing you will think of that would change my advice.

That concludes this thread. I hope you found my replies useful. You can move on with complete confident your rash is not due to HIV.
