We do not give specific advice either for or against PEP to prevent HIV. The decision should be made with a health care provider or clinic who understands the local frequency of HIV, treatment of HIV in such partners, and so on. I would make some general observations, however. First, "escort" usually implies an expensive female sex worker by appointment. Such persons tend to care for their health, use condoms consistently, get tested frequently, and have partners mostly at low risk for HIV themselves (men like you) -- and therefore are unlikely to have HIV. Second, with unprotected vaginal sex the estimated transmission rare of HIV to a male partner is well under one chance in a thousand. If we assume one chance in a thousand your partner has HIV, your HIV risk calculates to be under one in a million. Most people probably would consider that too low a risk to seek PEP; even testing for HIV is optional. However, it's up to you if you would like to see a local doctor or clinic to advise you.

The other info you provide -- penile hyperpigmentation, the condom "water test", or the lubricant used make no difference one way or the other. Except to point out that we always recommend against water testing of ocnodms. It's based on the urban myth of microscopic leaks that permit virus transmission. If a condom doesn't break wide open, protection is complete.

I hope this reply is helpful. Let me know if anything isn't clear.

Looking back over the years, this is your twelfth forum question and your second or maybe third about very similar exposures and HIV testing.  (Twelve isn't a forum record, but it's not far off!) Our advice has been pretty much the same each time. It shouldn't be necessary to ask about similar events again; you will know our advice ahead of time. So let's make this the last about such events. OK?

That completes this thread. I hope the discussion and the others have been helpful. Best wishes and stay safe.
