When i perform oral sex on him my throat hurts pretty bad for the next couple of days, could this be gonorrhea?

Yes, see a doctor.: It is possible to get gonorrhea in the throat, and many doctors won't think to test for it, as it requires special testing. Please see your doctor or go to a local city or state run health department for appropriate testing and treatment. Good luck.

No: Gonorrhea takes several days to incubate before symptoms occur. Seems like you're being too frisky with your technique.
