I really dont know to much about hpv, but first and foremost just be open and honest with him tell him exactly what you posted, if a man cares about you enough hell stay with you it wont mater, just make sure when you do decide to have sex you use condoms to protect him. Having a std does not make you a bad person, it means you had sex and there are tons of people who have them, and they are in relationships or married, so life doesnt stop because of it, if he doesnt stay then oh well his loss youll find someone who cares about you for the person you are not for what you have,
