As implied above, it is extremely unlikely you have oral gonorrhea. Even if you do, transmission by kissing have never been known to happen.
Thank you doc - last question - I forgot to ask if it can be spread via spit (i.e kissing)??
Welcome to the STD forum. I'll try to help.
Having performed unprotected oral sex on a male partner, it is certainly possible you acquired oral gonorrhea. (You don't say your sex, but if you're also male, the chance is a lot higher than if you are a woman -- but it's possible either way.) And certainly gonorrhea can involve only the throat -- in fact, if you didn't have unprotected vaginal or anal sex, only oral, your throat is the only site that could possibly be infected.
However, pharyngeal gonorrhea is not very common; and when it happens, over 90% of infections are asymptomatic. And gonorrhea does not cause post nasal drip -- only sore throat. A common cold is a far more likely cause of your symptoms than gonorrhea.
It's easy to be tested for pharyngeal gonorrhea; a simple throat swab is sufficient. You can expect a negative result. If positive, it probably still won't explain your symptoms. Even if positive, most likely the gonorrhea would be asymptomatic, plus a garden variety viral upper respiratory infection.
