I hate to sound like a public service announcement. But I just had a THIRD friend tell me that as a gay man (who regularly sucks other guys to completion), he went into his doctor for a full STD screening because of a chronic sore throat, and the (straight uninformed) family practitioner tested him for gonorrhea and chlamydia by giving him a URINE test... only.
THIS DOESN'T WORK.
When he and I talked and I expressed dismay, he followed up with his doctor, who insisted "people don't really get that in their throat - it's very, very unlikely". So he went to another doctor who swabbed. Sure enough... he had gonococcal gonorrhea.
I can attest that I personally have had gonorrhea in my throat (in the distant past) and I've known several other friends who have also. And of them - only about half had symptoms... the others just had knowledgeable doctors who knew their risk behaviors and wisely checked them in routine testing. **Also NOTE this infection is getting more and more resistant to antibiotics - and only a few still work, so let's keep on top of it boys!
If your physician or practicing clinic doesn't swab your throat - get a new doctor.
Ok - off my soap box.
