To follow-up, let me tell you a couple of things. assuming the woman was positive, the average probability of infection for insertive vaginal sex with an HIV positive woman is .0009. That means that the likelihood of you being infected is .0009%.
Male-to-female transmission was approximately eight-times more efficient than female-to-male transmission and male-to-female per contact infectivity was estimated to be 0.0009
This is because the lining of the vagina is a mucous membrane and hence more permeable than the outside of the male penis. However, statistics cannot tell you your not at risk. Only the test does. you need to take the tests. In my experience, i took rapid tests at 7th week to ease the tension then it was followed with the 13th week rapid test for the conclusive result.
it,s best not to rely to much on what people tell you about there sexual history because it may not always be the truth.You require testing as you know because you had unprotected penetrative vaginal sex and by doing so put yourself at risk.I would suggest a p24combi test that looks for both p24antigen and antibodies.Take it at 6 weeks to establish where your at.Given that the majority of people don,t have hiv and it,s much harder to contract it from a woman,your situation appears not to be high risk.You may want to test for other std,s aswell.All the best.
you have put yourself at risk from that incident which requires you to take HIV diagnostic tests. 3 months is conclusive.
What are the risks with having sex with a bisexual woman, I assume the same for a heterosexual woman? - a risk is a risk, i say you can never assume someone's status by gender or sexuality in HIV.
