I’ve had protected oral about a week and a half ago. I noticed later that afternoon, I have some pain kind of behind my left testicle. It’s not terrible and seems to hurt more when I move the testicle the right way. I’ve had this pain now for a week. I went to urgent care today and they did urinalysis and it was all completely normal. The PA mentioned epeditnitus or something and said that that is an infection of something surrounding the testicle. She did not feel like that’s what I had but prescribed me doxycycline in case the pain got worse. My question is, should I be concerned with Gonoreah or any other STI? Would you recommend any further testing? I should also mention, the person licked my scrotum and may have gotten saliva on the head of penis for 2 seconds before I put the condom on. Thank you, just nervous about engaging in regular sexual relations with my wife. 

Oral sex is low risk even without a condom, and no STD is possible via condom protected oral sex. And licking intact skin anywhere on the body, including the scrotum, is no risk for any STD; saliva rarely if ever transmits STDs and there also was no risk even if some saliva contacted you meatus (urethral opening). And no STD is a possible cause of symptoms like yours. Epididymitis can be due to gonorrhea or chlamydia, but the mild pain you describe doesn't fit. Also, neither epididymitis nor any other infection can start to cause symptoms the same day as exposure; 24-36 hours is the minimum time required. The main cause of mild or vague testicular pain is genitally focused anxiety -- i.e. worry or anxiety (for example, over a regretted sexual decision) magnifying minor symptoms or even normal body sensations that otherwise you would ignore or not even notice.

Presumably a urethral swab specimen or urine were sent for gonorrhea/chlamydia testing, right? If positive, it would have to be from some previous exposure (even from your wife?) and not from the condom protected oral event. Certainly no more testing of any kind is needed, and I rather strongly disagree with the PA who agreed to treat you with doxycycline. You can safely continue sex with your wife without worry.

No I wasn’t tested for any STI. She just did a urine test because I am currently having this mild pain behind my one testical. If I had any bacterial STI, such as the ones discussed, and had the symptom I’ve described, what is the likelihood I would have a completely normal urine test? In other words, without testing specifically for the STI, can I just take confidence in the fact that my urinalysis was completely normal? 

You might google chronic pelvic pain syndrome, for which testicular discomfort is a common symptom. Last time I looked, the Wikipedia entry was very good; also see information from the Stanford University dept of urology. As you'll see, it closely related to the concept of genitally focused anxiety.

That concludes this thread. Best wishes and stay safe.
