There has been no research on cunnilingus or frontage and HIV risk. What we know is that there are no known cases of HIV transmitted by such exposures. Must busy HIV/AIDS clinics probably have never had any patients whose only possible exposures were cunnlingus, frontage, massage, or genital contact without penetration (regardless of standing up or any other body position). That doesn't prove HIV cannot be transmitted, but if it does, it is extremely rare.

I don't recommend even being tested for HIV on account of such events, but of course you are free to be tested if you would like the additional reassurance of a negative test result. Certainly you should not take PEP and I would never advise it just for "peace of mind". And I doubt you could find a clinic or doctor willing to prescribe PEP in this situation, assuming you told the truth about your exposure(s) and reasons for worry about it. I know of no reason that past pancreatitis would raise the risk of more serious outcomes from HIV infection. But this obviously doesn't matter since you are not at risk for HIV anyway.

I hope these comments are helpful. Let me know if anything isn't clear.
