We can be sure because there are no docummented cases of hiv being transmitted via oral sex that have ever been substantiated or kissing,that,s why.Infact quite the opposite.There are plenty of studies that have been conducted to say that it is not a risk and those studies have been substantiated.
How can you guys be so sure u can't get HIV through oral? What about kissing with tongues and all that?

Oral sex doesnt pose a threat. You had protected sex and dont have anything to worry about.
