| Re: Having unprotected sex with a positive person you have a 1/500 chance of infection?
I'm not sure where you got the statistic but I think it does need some clarification: Typically, woman to man contact decreases the opportunities to contract the virus. Man to woman increases the chances. Receptive oral sex woman to man, or man to man is virtually a no-risk (although I would suspect that there are a case or two when the transmission occurs). Receptive anal, man to man, man to woman, increase the chances significantly.
Of course, we have to look at hypothetical risk vs actual risk. chris
