Your risk of acquiring HPV from receipt of oral sex is relatively low.  Oral HPV is far less common than genital infection and a single exposure rarely leads to infection. To your credit, you have been vaccinated and most oral HPV infections are due to HPV type 16, six, or 11, all of which are contained in the vaccine.  When they occur, most HPV infections resolve on their own over 1-2 years without consequences.  Further, there are no recommended tests for HPV in men.  My advice is to not worry and move forward.  EWH
