Vaginal fluid finger cut HIV risk

by curioussam73, Nov 02, 2009 04:55PM
My situation is follows:

About two weeks ago, I went to massage parlor and fingured a woman's vagina with peeled skin (about 3 mm) with second finger for about few minutes.  After fingering, I cleaned my finger with wet tissue.  

It was not bleeding after the incident but after pressing hard it bleed.  After reviewing this website, it sounds like this is a low risk activity to get infected to HIV.  However, I would like to understand my situation as why it is low risk as I have following thoughts coming and would like to understand scientifically.

1. Chances of vagina fluid getting into blood stream through peeled skin (skin was peeled about 3 to 6 hours).
2. Do body's existing immune/defence system fight HIV virus, in case HIV gets into peeled skin to blood?
3. How deep is the blood stream from finger?
4. How deep the vaginal fluid should get into bloodstream for HIV infection.

Above all questions are asked assuming the woman is HIV positive (status is not known- I pray she is not).  My anxiety is kiiling me...Please help.

Many thanks!

I strongly considered deleting your question without comment as it has been answer innumerable times in the past.  Instead, I will provide a brief answer with no follow-ups.  If you wish for more information search the archives of this site.

The scientific data from observation of not thousands but truly millions of exposures is that HIV have NEVER been transmitted by masturbation of an HIV infected sex partner,  This is irrespective of the presence of peeled skin, cuts, hang nails, rashes, etc - still never.  You are not going to be the first and for you to even be concerned is unfounded.  Similarly, testing is a waste of time and money.

With respect you your questions:

1.  There are many layers to the skin.  When there is trauma such as a cut or scrape healing begins immediately.  Thus, no risk.  
2.  This is a theoretical question for which there is no scientific answer.  The body does not use a single host defense mechanism to fight HIV but many.  In combination, this translates to no HIV transmission through masturbation, even in the unlikely circumstance that your partner had HIV.
3.  ???
4.  Again, not a question that makes a whole lot of sense.  Please remember that when HIV has been spread by non-sexual ways, it is injected into the blood stream, not simply splashed or otherwise applied.

This ends this response. There will be no further answers.  EWH
