The exposure is sufficiently low risk that testing really isn't needed, except for the additional reassurance you may gain from the negative result. If you choose to be tested, the timing depends on the test you choose, or offered by your doctor or clinic. Three months is always safe, but virtually 100% accurate results are available by 4-6 weeks. See

Thank you for all your sound advice. Will probably contact CSW and ask directly just to be sure (high end escrot service).
One last question. How long to wait until I get tested?
Best wishes and have a great week.
From above: "...you really shouldn't be worried on account of this single event."
Thank you Doctor. So basically it would be fair to say that I need not to loose sleep over this incident and carry on?
Welcome back to the forum. Thanks for the clarification below. I assumed that by "receptive" you meant you were the oral partner, but it's good to know with certainty.
CDC has published an estimate that if a penile parther has HIV, a partner performing fellatio has 1 chance in 10,000 of being infected. That's equivalent to performing oral on infected men once daily for 27 years before transmission might be anticipated. Most experts believe a few such transmissions have occurred, but only a very few in the 30 years of the known HIV epidemic in gay men. And this is only with known infected partners. Statistically, it is most likely your partner doesn't have HIV; even among the most sexually active gay men, most aren't infected.
If I correctly recall the data I once saw, the National Safety Council estimates the lifetime risk of being struck by lightning (in the United States) at 1 in 17,000. So it's fair to conclude that an exposure like yours carries a risk comparable to that of a lightning strike.
If you remain worried, have an HIV test -- especially if you have been sexually active and not tested in the past 1-2 years. But in the meantime, you really shouldn't be worried on account of this single event.
However, I would strongly advise you to modify your sexual safety practices to include always asking partners about HIV status before having contact, and avoid going ahead with partners who are positive (and not on treatment), don't know, or are evasive about it. This isn't perfect protection, but most infected people don't lie when asked directly, so it provides substantial protection.

Clarification.
I meant that I was performing the oral sex and received amount of semen in mouth. Now, I've by your colleagues over at the Intl Forum that saliva deactivate the virus and that the risk, even if partner was HIV positive, would be from 0 to 0,04? With those odds, would it be accurate to say that thereis more chance to be struck by lightning than to get HIV?
For context, I am in Latin America.
