Hello - in China five days ago i had sex with a prostitute. she gave oral unprotected sex to me for 5 mins, kissing also. We then had sex with condom. condom did not break. Concern based on: 1. her profession, is HIV at high levels in the Chinese sex industry? 2. how soon can i test?. i talked to a doctor in china who advised there was a window in the fist week, then again six weeks later etc. 3. i have read about fake condoms in China, any info on their effectiveness?
