First of all, is this your only account here? Second, whether it is or it isn't, you've surely read what are risks for HIV. Having unprotected vaginal or anal sex or sharing IV needles to inject drugs. Air and saliva inactivate the virus. So, man. You never even had a risk. Condoms sliding up are not risks. ONLY the head of your penis needs to be covered. And third, no. the vaccine doesn't affect hiv.
