I messed up a double-negative statement above. I meant "...if the condom overtly ruptures (i.e., with the penis completely uncovered), STD/HIV transmission risk is higher, but micsoscopic leaks probably make no difference."
The brief reply is that no, I see no particularly unsafe elements to your exposure. Of course, there are no data -- i.e., nobody has done research (and nobody ever will do studies) to determine whether such details of how condoms are applied and removed, or whether a condom leaks a drop or two of water after sex, have any influence on HIV transmission risk. We know that if the condom doesn't overtly rupture (i.e., with the penis completely uncovered), STD/HIV transmission risk is higher, but micsoscopic leaks probably make no difference. Certainly there is no reason to suspect that how a condom is rolled on and off makes much difference. Even with condoms, it is almost impossible to avoid some skin-to-skin contact with a partner's genital secretions, yet HIV transmission doesn't occur.
In summary, you had sex with a partner who most likely does not have HIV (which now is rare in Thai CSWs); that even totally unprotected, vaginal sex with an HIV infected person carries an average risk of 1 HIV transmission per 2,000 exposures; and that properly used condoms provide virtually 100% protection. And yes, I consider your condom use to have been proper and fully protective.
You don't need HIV testing on account of this event. But if my reassurance doesn't settle your concerns and you will sleep better with a negative HIV test, it's fine with me.
