HIV Potential?

Doctor,  I had protected insertive m2m anal sex with an anonymous person 5 weeks ago.  I have to assume that he was HIV positive as he wanted to receive without any protection.  This was at an adult theater frequented by men who have m2m sex.  I had shaved my genital area approximately 2 hours before this encounter and noticed after the m2m encounter that there was an open sore approximately one eight of an inch in diameter from shaving at the base of my penis which was not covered by the condom.   I did not see any blood, but the sore probably made contacted with his anus.  Ten days after the encounter, I have developed a headache which continues to date at the 5 week mark. No other symptoms (fever, sore throat, swollen glands etc) are present.  I have read that since I was protected, the risk is low but the headache has me very concerned since I rarely have headaches and never had one lasting this long.  I plan to get an HIV test at the 8 week mark but the wait and headache is worrisome.  What was my potential risk and is the headache indicative of a potential initial HIV infection?  Thanks.
