In general, people seem to usually tell the truth when it comes to informing partners of their HIV status, and that's probably especially true for partners (or clients) they know. So it is very likely all three women are HIV negative; and you'll know for sure about the last partner in the net day or so. Even if one of them has HIV (and not taking anti-HIV drugs), your risk would be around 1 chance in 2,500. All things considered, I would put the chance you were infected at no higher than one chance in a million.

Of course the risks for other STDs are higher, but still fairly low -- although this depends a lot on the nature of your partners' other commercial sex contacts, whether they have been tested recently, and so on. Over the next 2-3 weeks you should be on the alert for abnormal discharge from your penis (suggesting gonorrhea, chlamydia, or nongonococcal urethritis) and for genital area sores (herpes, syphilis). Assuming any symptoms, of course get medical care immediately. If no symptoms, you could have a valid gonorrhea/chlamydia urine test after 4-5 days. Syphilis and HIV blood tests would have to wait:  you could have initial testing after 2-3 weeks, when negative results would be partially reassuring, but you'll need to wait until 6 weeks for conclusive results.

I hope these comments are helpful. Let me know if anything isn't clear.

That completes the two follow-up questions and replies included with each original question and so ends this thread. Stay mellow -- the odds you caught HIV are minuscule. (And you may be further reassured to know that in the nearly 17 years of this and our preceding forum, with thousands of questions from persons worried about a possible HIV exposure, nobody has reported they tested positive. You're not likely to be the first. If and when that happens, almost certainly it will be a genuinely high risk exposure, not a minor or low risk exposure of this sort.

I hope the discussion has been helpful. Best wishes and stay safe.
