It may discourage HIV testing and it may deceive the public into believing that those who engage in prostitution are not HIV infected. If you have sex with a prostitute or with anyone and you do not know their HIV status, the best prtection for HIV and other diseases during a sexual encounter is to perform safer sex or sex with a properly used latex condom.
Safer sex can be any activity where there is no exchange of bodily fluids.
