Chance of hiv from giving oral sex with almost no precum from another male. i also have braces and he said he was negative.

High risk behavior: Oral sex with braces is a high risk behavior because the braces will almost always leave small cuts on your gums(mucous membrane) that the HIV virus can easily invade. The sex partner said he was "negative", but unless there was a HIV test report stating the same it becomes the "second biggest lie in the world.". Get HIV tested.
