there are no applicable percentages. there are just too many variables to consider. needless to say this person has two (perhaps more) sexually-transmitted diseases and you apparently had unprotected sex. this is a high-risk situation so it is advisable for you to be tested periodically for hiv and other stds until enough time has past that you are no longer considered to be "at risk".
i have had sex one time with a person infected with hpv. what is the percentage i will get hpv. they have genital warts.
