I personally wouldn't put much stock in sensationalistic media reporting.
Here's what the Center For Disease Control (who happens to be the worlds top authority in HIV) says.
I'm not into Greek so I'm just talking vaginal intercourse.
Worst risk is to the one receiving, and that risk is 8 in 10,000.
Which means a 1 in 1,250 chance of you being infected having vaginal intercourse with an infected partner.
If you were at a Vegas blackjack table and the dealer had a 1 chance in 1,250 of beating you, but you have a 1,249 chance that you beat him, you would make the bet!
