OK,thank you so much for help.
That's correct.Stop worrying.
"virus" you said here means vaginal fluid contained HIV,right?
I feel better after your words ,thanks a lot.
You don't have to be concerned as you had no risk,but to answer your question--the virus is extremely fragile outside the human body,therefore it begins to become inactive very quickly and loses it's ability to remain infectious.
HIV transmission always takes place as a result of exchange of body fluids INSIDE the body, NOT outside. The situation you described, does not put you under hIV risk, regardless of seconds, milli seconds or micro seconds
