I heard that once the hiv positive liquid contacts air,it would not be totally killed untill s few minutes,but it would be unactivated,i mean,uninfectious as soon as several ten of seconds.
My risk is that,I had sex with a prostitude,and after two hour ago,I found that there was an old scratch near my penis 20 minutes before the sex.Then,I remembered that wound(not bleeding then,but ozzing some liquid),contacts the MIXTURE OF THE VAGINAL LIQUID AND THE CONDOM GREASE,and before it contacted my wound,it contacted with air,,and after it touch my wound,it also kept contacting the air untill I have my bath two hours later.
DO i have risk of hiv?
