Three months ago I received unprotected fellatio for no more than five minutes. No erection, no ejaculation. Of late, more urinating (prostate cancer surgery a while ago). No burning, no pus, no discharge. What STDs am I at risk for?
Welcome to the Forum. Both the timing of your exposure (and the interval since then) and the nature of your exposure and symptoms make STD unlikely. Few STDs are transmitted through receipt of oral sex and when they occur persons typically become symptomatic within a week of the exposure. The symptoms they cause are burning on urination and/or urethral discharge. The two STDs which do occur due to receipt of oral sex are non-gonoccal urethritis and gonorrhea. When you are seen for this, these problems are easily tested for and treated if present.
On the other hand, urinary frequency is a common symptom of a urinary tract infection and UTIs are rather common after urological therapy and/or in the setting of prostate disease. If possible the best place to address this is the urology clinic. EWH
