This is the HIV forum so will answer that for you. HIV is really transmitted in specific ways. They include having unprotected vaginal or anal sex with penetration or sharing IV needles to inject drugs. Air and saliva inactivate the virus. ONLY the head of your penis needs to be covered which yours was during intercourse. And your giving her oral sex will also not transmit the virus. Air and saliva are present in oral. So you had zero risk for HIV
