Dear Doctors ,

I had an encounter with a lady which i don't know her HIV status , she is not sex worker , but i feel she has in relation with another man ,from India ,my experience was , we were in a car she massaged my penis with bare hands and had blow job for few seconds lets say maximum 2 minutes, the issue was at the heat of the moment I fingered her vagina , when i take my finger out i had little blood on my finger ,she said she was on periods , my finger doesn't had cuts , i immediately stopped the car and washed my finger , the issue is she touched  blood contaminated finger and wiped with her bare hand before i washed my finger , and without washing her hand after few minutes may be 3 or 4 minutes she touched my penis again ,there was no visible blood on her hand or I didn't notice at the heat of moment , all this happens inside the car and day light A/C was running on the car, I am really worried about now thinking about HIV infection , she massaged my penis head and touched opening of penis after touching blood , i am circumcised male, i am really worried

1. Does the blow job and touching and massaging my penis after touching blood is there is chance of getting HIV ,even 1% risk is there ?

2. will HIV virus dies immediately after exposed to air ?

3. Can I resume my normal life , having unprotected sex with my wife or do i need to take test , if i need to take test when i need to take this happened only 3 days before .

You needn't be worried at all about HIV. You describe a partner who is unlikely to have have it, but even is she does, you may misunderstand HIV transmission risks. There is never significant risk from sexual exposure unless there is unprotected (no condom) penile penetration into a partner's vagina or rectum. Hand-genital contact and oral sex are risk free. The same is true of finger penetration, regardless of menstrual blood. 

Those comments pretty well cover your specfic questions, but to assure no misunderstanding:

1. Not even 1% risk -- zero risk for all practical purposes. In the 40 years of the known world-wide HIV epidemic, nobody is known to have been infected from the kinds of contact you had.

2. Wrong question. HIV does indeed die with exposure to air, but probably not instantly. But the important thing is that such contact is not known to transmit HIV. The bioligical reasons, like HIV survival in air, don't matter.

3. You can safely continue unprotecte sex without worry, and without testing for HIV. 

I hope these comments are helpful. Let me know if anything isn't clear.

Dear Doctor

Thanks for your advise and gives me valuable information , I would emphasize that she touched by finger which contains her blood and wiped my finger after few minutes without washing her finger she touched my penis and opening of my penis will it poses any risk , I am sorry I might be overthinking ,

Perhaps it will also reassure you to know that in the 16 years of this and our preceding forum, with thousands of questions from people worried about an exposure that might have put them at risk for HIV, nobody has ever reported that they later tested positive. You won't be the first! If and when that happens, I expect it to be from a genuinely high risk exposure, like unprotected intercourse with a known infected or high risk partner.
