Thank you in advance for offering up your expert advice. I am a 46 year old male and saw a female CSW seven days ago. I received unprotected oral sex. Everything else was protected by a condom. Five days later I began experience burning while urinating. The pain is at the very tip of penis and honestly feels more like an injury than something STI related. No discharge and no other symptoms. It isn't getting worse. Should I look into this more and get tested or give it a few days? Thank you again!

As you apparently know, oral sex is low risk for STIs:  not zero risk, but much lower chance than by vaginal or anal sex. In general, pain alone is rarely a symptom of urethral/urinary STI in men; the main symptom is discharge. However, it is conceivable you acquired gonorrhea, nongonococcal urethritis (NGU), or herpes due to HSV type 1. But as just implied, lack of discharge is evidence against the first two, and if it were herpes, the pain would be worse and by now you probably would have had obvious herpetic blisters or open sores. An injury doesn't seem likely given the delay of 5 days before onset of pain.

It should be safe to wait 2-3 days and see what happens -- discharge, sores, or anything else. If not and the pain subsides, probably you can just let it go. OTOH, if it persists -- or if you'd just like the reassurance of knowing for sure -- see a doctor or clinic with experience in STI management. Or you could go directly to a lab for a urine gonorrhea test -- but that won't rule out NGU, which can be caused by normal oral bacteria. (Gonorrhea testing usually includes chlamydia automatically, but chlamydia is acquired very rarely by oral sex, if ever.)

Let me know how it goes. In the meantime, I wouldn't be seriously worried. I hope these comments are helpful.

HHH

That concludes this thread. I hope the discussion has been helpful.
