Good afternoon doctor, first of all i would like to aplogyse if i make mistakes writing because english is not my native language. Yesterday i had sex without protecction with my boyfriend. I am the top and he is the bottom. He did the HIV test on February, 8 month ago and the result was negative. From that month to August, he was using Prep and had sex without protection with his ex boyfriend and whit a friend of him. He says they showed him their VIH exams, and they were negative. Even when he says he dont have any STI and he dont have VIH I would like to know how high is my risk of having VIH if it were the case he is VIH positive.
