The risk of being infected with hiv after recieving oral sex with a condom on is essentially non-existant. There have been no reported cases of this happening.

Coming into contact with vaginal fluids (i assume you mean on your skin?) is harmless, unless the skin was broken. If there was a fresh open cut or sore on the skin, hiv can pass into it and into your bloodstream. But again, that is an extremely unlikely scenario and there have been no reported cases of hiv transmission that way.

Do not rely on symptoms to diagnose hiv. If you're worried, get tested three months after your last encounter.

I was involved in a similiar situation, and it ruined my life! All I did was worry and worry for months. I started smoking,(i lost a ton of weight), my grades dropped, ... The supression of my immune system caused me to have a ton of symptoms: geographic tongue, severe heaedaches, wierd blotchy rashes, tightening of throat, constant fatique, severe nightsweats, and neorapathy problems that included my vision and the tingly sensation in the hands. Dude I thought I had it, there was nothing anyone could say that would convince me otherwise.... All you need to do, is just get tested, and its definitive at 3 months, but u should still get another test at 6. - dont worry, be happy man ;) trust me, you'll live a lot longer........

Indeed. Symptoms are not a reliable way of diagnosing hiv, not at all. And in fact, when somebody worries about physical symptoms, they begin to think intensely about every litte thing which occurs on their body. From a little pain in the arm, to a sore throat, to an unusuaully long fart, if someone is really worried, they often attribute it to hiv.
Your risk was very low. If you are worried, bite the bullet and get tested after three months, and yes, at six as well if you like. That's the only way to know for sure.
