I had a laps in judgment and had unprotected sex with a woman. She is white and from what she told me of her background she had only had 3 partners in the 6 years she was divorced 1 of which there was no sex due an injury. Previously I was in a 2 1/2 year relationship after being divorced. I have read alot on the forum that it is highly unlikely that I could contract hiv from vaginal Intercourse from one exposure. I have never had an std I had no open wounds on my penis, can you give me some piece of mind until I get tested. I had a head cold approx. 3 days after could this be symptoms of contraction? How soon can I test?
