a more generalized question

[Confused1530]

So a general information question.  The CDC says that there have been no documented cases of HIV receiving oral sex but some in giving oral sex (with ejaculation in mouth).  What would the actual percentage be of performing oral sex on an infected person and getting semen in your mouth?  What's the reason behind oral sex being safer than vaginal, anal, blah blah blah.  I would think that since HIV is transmitted through semen, that it would be just as risky.  No, I am not concerned that I have HIV now, just wondering for informational purposes.  Thanks

Just to expand on Teak's answer the CDC reports everything that has ever been said about HIV transmission. I believe that you can even find a case on the CDC website where someone claimed they were only kissing and got HIV. But it is known...scientific fact that kissing does not transmit HIV.
So the CDC will say this or that, but many studies have shown that HIV through oral sex is not a risk...giving or receiving.

There has never been a verified documented case of HIV from oral sex. Saliva has over a dozen different enzymes and proteins that inhibit HIV from transmitting.
