Do i need pep for protected sex with a unknown status person. worried he may do high high risk behaviors but used condoms. two times?

Probably not: PEP decisions are made case by case, depending on details. For example, what do you mean by "may do high risk behaviors"? Also local frequency of HIV in various risk groups. With a heterosexual exposure plus condom for vaginal sex, I doubt PEP would be recommended. But you'll need to see a local HIV expert, or contact the local or state health department.
