You were advised on your thread a year ago that oral sex isn't a risk for HIV. Nothing has changed. Protected or unprotected, oral sex is not a risk.
Do not have unprotected, penetrative anal or vaginal sex with someone of unknown status, and do not share intravenous needles with other people, and you will NEVER have to worry about HIV.
Status of the hooker doesn't matter - you can't get HIV from any of the activities you mentioned.
