If you had brief insertion, the odds are EXTREMELY low that you got HIV. However, the fact that she allows clients to have penetrative sex without a condom means that she is at higher risk for having HIV and STDs. Again, brief penetration would be very low risk.
It sounds like you are very concerned about your wife, though, so you should abstain from having intercourse with her until you are tested for HIV and STDs, for her safety.
For future reference, washing your hands, body and penis with sanitizer or soap after a sexual encounter does not kill or prevent HIV or STDs.
a few days ago I had sex with a prostitute for no comdom
If you didn't penetrate you had no risk. If you penetrated for a few seconds you probably had no risk. hiv is dead in air so you wasted your time washing or sanitizing dead virus afterwards.
