Can i get hpv, sti, hiv or any type of disease from some who is clean and they have the prof they are?

Be careful, friend!: Use barrier protection if you have to ask this question. Nobody is certifiably free of HPV -- there are dozens of strains including some that we don't test for that can give you at least warts. HIV testing is reliable except very early, but do you want to bet your life? Who's got proof-positive they didn't meet gonorrhea yesterday? Keep practicing good habits -- be a gentleman.
