UNPROTECTED SEX WITH CSW IS A HIV RISK, TEST AT 3 MONTHS FOR A CONCLUSIVE TEST POST POSSIBLE EXPOSURE(WITH NO EXPOSURES IN BETWEEN) , She is a csw but do u say that u were her only customer after 2 months and do you also say her only possible exposure was 2 months ago( and still a 3 month test is only proof of conclusitivity.) Others would definitely advise u to mindlessly engagge in all kind of sex acts but only with condom thats how they boost condomn sales. I dont work for them, SEX outside marraige/multiple partners of unknown status is all a risk, be safe , marraige is ur best bet.
Be sure to test at 3 months also openess about ur status to all possible partners. I hope u re - ve and stay that way.
Ignore my suggestions if u want only qualified docters I am not a docter.
Obtain a conclusive result at 3 months post exposure and ignore the other poster. It doesn't matter with whom you have sex with or how often as long as you use latex or polyurethane condoms consistently and correctly which includes using plenty of water base lube.
