And Mark makes another valid point.
Well, that's a nice table. What does it tell you that you don't already know? Since the start of the epidemic, gay men have accounted for over 500 000 of HIV infections in the US. In contrast, men that claim to be heterosexual account for only 60 000 of HIV infections - that's over 25 years of epidemic. In the US, HIV is very common in gay men, but rare in the general population.
Dear Teak,
The problem is that study don't makes distinction between anal heterosexual and vaginal heterosexual. Because if people became infectede had anal heterosexual then it's like a gay risk for the existence of rectal fluid.
Mark makes a good point by the way.
Freak, you can ask other experts as well - they will give you the same answer as I did. A cr@pshoot is all it is. There are many factors that affect the odds, but in the end it is still a cr@pshoot. You'll miss the 67 shots, but nail the 68th. I know basketball is a poor analogy, yes it takes practice (unlike HIV), but I can't think of another one right now.
For your information, I did not get a warning from Medhelp. :)
And the rectal fluid has more viral load than BLOOD. This explain, for me, why in Africa and among the gays of USA HIV is a not a too rare disease.
