There is no real risk for gonorrhea.
It is widely believed that oral gonnorhea is not transmitted via french kissing or anilingus. That is also the opinion of Dr. Hansfield, a respected medical expert of the STI field.
Some newer studies suggest that theoretically oral gonorrhea might be transmitted via saliva, but that is still highly debatable and there are no definitive studies to prove it.
Your risk is theoretical, no need to worry or get tested.
