There are risks in everything we do in life. Driving a car, flying, sex whatever we do. Risk for catching HIV is actually about the same as being killed in a car accident. ( 40 to 50 thousand a year.). Actually if you are a white male who has sex with white females over age 24 your odds of catching HIV are very low.

African Americans and youth are the highest risk also for males oral sex is low risk.

Just use common sense I frequent Strip Clubs and I can tell you there definitely is riskier behavior going on than with most providers. The strippers tend to be more willing to take more risks than Indys. Don't know why maybe alcohol. Anyway I believe if the story here is true that it is sad for all involved and proof that some people just don't give a shit about anything but themselves.
