Vaginal fluids...HIV infectious?

"Vaginal fluids...HIV infectious?"

Suppose I want to have sex with 2 women.
After having sex with the 1st woman (which has HIV),
I then have sex with the 2nd one without changing the condom.

I have been told that vaginal fluids is not infectious
outside human body.
So, is the 2nd woman going to be HIV infected?

You change condoms inbetween switching partners.

So, in the case mentioned above (with 2 woman) the vaginal fluids ARE infectious.

What about my case I posted a week ago:
>>>I was with a prostitute...yesterday.
>>>She changed the 2nd condom for me afrer removing the 1st.
>>>But while removing the 1st she was actually touching her vaginal fluids.
>>>So by unrolling the 2nd condom she was touching the inside of the
>>>2nd condom with her hands having some vaginal fluids from the 1st condom.

In this case you have told me that vaginal fluids AREN'T infectious,
because they are outside of the human body...

But after wearing the 2nd condom we had sex...
(this maybe wasn't clear enough in my 1st post)
So by wearing the 2nd condom as mentioned and then
having sex... is it possible to be HIV infectious?

Go back and reread the replies you were given. The answers aren't going to change.

Thank you again for your answer.

I'm trying to understand how exactly the virus is been transmitted...
And why my case is not a risk-one...?

It depends of the quantity of vaginal fluids my penis has been contacted with, I think...
Am I right...?
Because i have read somewhere that saliva is also contains HIV...
but in such amount that cannot be transmitted
