hello doctor recently i gave oral sex to a prostitute and since have been worried of getting hiv. I know other sites consider it a low risk, including the cdc website, but why do you guys consider it no risk? I know theres possibility of getting infected through small cuts in your mouth such as from flossing, is this true? does it matter that i tasted a substantial amount of vaginal fluids in mouth during this incident? What's the responsible thing to do, should i test?
