Pick a side ))) The chart does suggest that giving oral is not risk-free - because it isn't.
The short answer is no risk at all
what im gonna say is: oral sex will be a risk if and only if you have a FRESH sore/broken skin and it is bleeding at that time as well...the case could be: u have a sore/broken skin ( not fresh ) and are having a very hardcore oral sex that make it open and bleeding :)
Ahhh Teak, you really are sticking your neck out with this "Zero risk" stuff about oral sex. It is not Zero and you really should modifiy your responses. You are baseing it on two studies years ago. No Dr. in the world would say a person who takes infected fluid in the mouth would be at a ZERO risk of possible infection. I hope others will not engage in risky behavior base on your false postings.
do you know the stats or percentages of risk behind giving oral with good oral health?
Then test. You asked a question and it was answered. If it will make you feel better go test collect your negative result so you can move on.
