Hi. I'm sorry if this has been addressed before, but I can't seem to find it. I am a woman who had a sexual encounter with a man of unknown hiv status. We used a condom for penetration, but up until then we were unprotected, so there was definitely contact between our genitals and fluids (vaginal and pre-cum) and for quite some time. Am I at risk?
Thank you so much
Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV from contact with pre-cum and vaginal fluids. From the information given, this scenario is determined to be Low Risk (Evidence of transmission occurs through these activities when certain conditions are met). This activity is deemed to be low risk because there is a potential for HIV transmission as this involves an exchange of body fluids.
For a risk to exists, specific HIV positive fluids (semen, pre-cum, vaginal fluid, rectal fluid) must come into direct contact with the blood stream of an HIV negative person. Most of the body's surfaces are "dry" skin and they don't allow HIV to enter the body. "Wet" skin (or mucous membranes) is more vulnerable to HIV and these include foreskin and urethra in penis, cervix, vagina, anus, rectum, mouth, throat, open cuts and sores. 
Recommendation: Refer to Physician for HIV test.
