Had a brief anal penetration, did I get HIV?

[jorandiguz]

I'm heterosexual but had a curiosity to try it with a man. In a party I met this guy and after drinks we ended up kissing each other and I gave him a short oral ( about 5 to 10 seconds ). He didn't eyaculated or had precum. He started to give me a massage on my back and suddenly I felt he penetrated my anus. I immediately walked out. That brief penetration was for about 2 - 3 seconds. Now I know for sure I'm not gay because I didn't enjoyed this acts and second I'm scared to death with the idea of having HIV. I read that by kissing there is a very little possibility and my mouth was totally healthy at that time ( not bleeding ). Also giving oral for such a short period of time with him not eyaculating or having precum is not a big risk ( well, that's what I have been reading ). But what with that brief anal penetration? What are the chances there.
Please help
Thanks.

Statistics don't tell you a thing. Only testing will give you your status.

thanks, but what are the statistics per act. I read that is 1 in 200, which means a 0.5% probability. Is that true, provided the fact of no eyaculation, precum and only 2-3 seconds? I just want to know the statistics playing in my favor at the time I'm going to test. Thanks

Get tested for HIV but more so STDs.
