Flu like symptoms soon after brief sexual encounter

[xyzface]

recently went back to a girls house i had been with before after a drunken nite out..all that was performed on me was masturbation as she refused to go any further. However i did pleasure her briefly with my fingers and oral sex..now 2 days later i have what seems to be a terrible flu with sypmtons including headaches,muscular pain,weakness/tiredness and a bit of a cough. The flu has been going around my area recently with some of my friends having had it..as well as the swine flu scare. But yet i am still paranoid.. i dont appear to have any other symptons like pain when urinating etc.any help would be greatly appreciated!

Not a STD.

It is just your paranoia taking over.  You would not get symptoms that strong only 2 days after.  Either way, getting an oral std is not common at all.  You most likely have the flu from your friends.  The best way to ease your mind is to go to a doctor and get tested.  But I don't think it is necessary.  That would be your choice.
