I've been having the same problem for a few years now, and have had an equally hard time getting answers, though I've got a theory or two. I'm gay, so all of the following is male / male.
I was in a 5 year monogamous relationship in my 20s, and shortly after turning 30, found myself single. I soon started seeing somebody new and got strep shortly after we began having oral sex. After that it stopped for about a year, and then recently I began seeing somebody new again, and got strep 3 more times, and then it stopped again. I've continued seeing this person, and the strep seemed to have calmed down. Then recently, I had oral sex with somebody else (with the consent of all parties--judge me if you will, I'm not at all ashamed to be a sexually active, honest person) and I have strep as I type.
My best theory--and this doesn't explain everything--is that, as I understand it, strep hides in the recesses of the tonsils called "crypts," and people with more and deeper crypts are more susceptible to recurrent infections of strep. Often, a dose of antibiotics will get rid of the infection completely, but for other times traces of the bacteria remain in the crypts. This is why doctors often recommend tonsillectomies for recurrent strep. My theory is that fellatio often dislodges some of that bacteria and reactivates the infection.
Of course, that doesn't really explain why after a while with a partner, the infections seem to stop, and a new partner seems to trigger it all over again. Maybe a new partner's penis introduces new kinds of bacteria, that form a hospitable environment for the dormant strep bacteria to reemerge? And then eventually you adapt? Maybe that's crazy. I don't know. I'm not a doctor. Just thoughts.View Thread
