I think I have been exploxed to HIV virus about the month ago, I don't have any symtomps ( not that I have noticed). Im suspecting that my partner is lying about his stutas....I've been seeing HIV related signs to him, but he claims he's negative, and im getting more and more curious as days go by, I also have a o- blood group which i have read that with this group type the chances are close to nothing, and reading that unprotected anal sex is a high risk...before i go for test I want to know what are th chances of me being infected, over a 1 time of unprotected anal sex. Im bottom, and my partner had his sperms inside me and im worried....what are the chances that even with my o- type i might have got the virus
