HIV FROTTING VAGINAL FLUIDS

Question

Hi Dr. I was at a strip club last night. I got a private dance, and the girl got completely naked, I was in my boxers (underwear). At a point her vagina was right on top of my penis (I still had my boxers on). After the dance finished I noticed my boxers were really wet from her vaginal fluids. What is the risk of HIV from here vaginal fluid coming into contact with my underwear(Note: I was erect the entire time)?

You never had an exposure. 

HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.

HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
Mother to child

Why do you say so? What he said was that if the vaginal fluid was contagious and it got into my mucous membrane then there might be a problem

Teak · Answer

You never had an exposure and the Urologist doesn't know what he's talking about.

Hey Teak, so i went to a urologist to talk about this situation. He said their is a chance of infection if the vaginal fluid goes into my mucous membrane.. Any opinions?

Teak · Answer

No risk, the above reply tells you how HIV is transmitted.

Hi thanks again. My penis definitely came into contact with her vagina, just that my boxer was in the middle of it.. No penetration just contact with the lips.. Same thing?

Thanks for the quick response.. My greatest fear is that my boxer (thin, cotton) was acting as the only barrier between me and her vagina (which as I mentioned was soked)
