I need a reliable answer, thanks alot.

I had a risky behavior last august(yes,almost one year ago). She is a kind of sex worker(im not sure if she provide real sex for others,but she's main job is doing massage).She firstly did a hand job for me then sucked my balls(didnt suck my penis) and then rubbed my penis by her genital(I think it didnt touch my glans (glands) but im not 100% sure). Then she licked my anus.
Now Im wondering some issues.
1.Any risk for sucking the balls?
2.Any risk if her genital touched my penis and her fluid touched me?
3.I know saliva is safe, but how about if she has a cut or cuts in her mouth or tongue so the blood can make me in danger because she licked my anus?And how about if i have cut on my anus(im not sure if there's small cut)
4.Any risk that I dont know?
5.Do I need a test?
I have checked some websites including this, almost all of them said my risk is low or zero.But the us CDC and the WHO's website says oral sex(including licking) is dangerous(but low).So i really want to know the real situation im facing, and if im safe why the two official sites say so.

Thank you very much for helping.

Welcome to the Forum. These are all no risk activities that do not require testing.  You can be confident that you are not at risk and do not need testing.  Please realize that agencies such as the CDC cannot provide the sorts of personalized messages that we do and, perhaps more importantly, feel that because of governmental affiliations, cannot "afford" to ever be wrong.  As a result, there is very little that they will describe as zero risk despite the lack of evidence that any particular activity has ever caused HIV.  

In answer to your specific questions:
1.  No risk from sucking your scrotum.
2.  No risk from touching or contact with genital fluid.
3.  No risk, even if she had cuts and/or blood in her mouth.
4.  No, no risk.
5.  No, there is no medical reason to test relate to the exposure you describe.

Hope these comments help. You can relax. EWH
