Hello
Your ejaculated fluid gathered in the tissue and that was already used for one else ( may be HIV infected person semen). This is the cause of concern that HIV transmitted through your
urethra.
HIV has been demonstrated in seminal fluid as well semen both within infected mononuclear cells and in the cell free state.
If HIV infected person have
urethritis and
epididymitis virus concentration increases.
I want to say that , if that tissue used ( already ) were of a patient of HIV infected , also having urethritis chance of HIV infection is more ,but not necessary .
It depend on many conditions as more virulent strains of virus ,
viral load , advanced stage-disease , antiretroviral therapy.
In my opinion get in rapid P 24 nucleic acid amplification test for HIV confirmation .
Antibodies to HIV infection begin to appear within 2 weeks of primary infection ( contact with used tissue).
Hope this will help you.
