Hi doctors, let me say I have searched this site and have found great comfort regarding situations I have worried about before. Even in my current worried state, I have found many posts similar to mine ,and the replies were comforting. However an anxious mind likes reassurance. My situation is I have had 4 encounters between the first week of September and the first week of October. They were with a crossdresser csw. All 4 times there was no oral, no anal. Only hand contact. The person would start masturbating my penis, and then tell me to masturbate myself until I ejaculate on him. While I was masturbating he would masturbate himself and would put his finger in his mouth and then switch to rubbing the tip of my penis with his finger and masturbating me for a few moments before switching back. He never ejaculated but there may have been pre cum. I am concerned because now, a week after the last encounter my left testicle is achy and sore to the touch, no burning when urinating, no discharge. I am going to see my urologist as soon as I can get an appointment. With the activities and contacts I mentioned, am I at any risk for chlamydia, gonnorhea or any fluid transfer sti. For what it's worth the crossdresser showed me test results from the last week of August and she was neg for all sti. Thank you

Welcome to our forum. Thank you for reviewing other interchanges with previous clients. We make them available for the purpose of allowing our clients to see that, typically they are not alone and to obtain information from the what we have said to others. I suspect that, having seen replies to somewhat similar situations, you can anticipate what I’m about to tell you. The interactions you describe were no risk events. As you already know, mutual masturbation is does not put a person at risk for acquisition of any STI including HIV. The fact that your partner put her finger in her mouth during the process of masturbating with you does not change that assessment. ---

Update, went to urologist. Had ultrasound. Told me slight epididymitis . Urinalysis showed everything normal except for trace leukocyte esterase. Prescribed me bactrim antibiotic. Your reply initially gave my anxiety some relief. This urinalysis result and  epididymitis has given me some worry. Does this point toward sti?

While STIs occasionally cause epididymitis, most is not caused by STIs but routine urinary tract bacteria.  Bactrim is a great drug for this.  I would take the Bactrim as recommended.  EWH---

Thank you for the replies doctor. I was going to save this last follow up for when I get the results of the bacteria culture my urologist sent out , but my anxiety is through the roof right now. I have never had leukocytes come up in a urine test before. Is the fact that it said "trace" leukocytes and neg for nitrites lead in a direction that this is not an STI?. I failed to mention I am married for 17 years, I am 43 years old. My biggest concerns was the hands back and forth stuff. The person going between masturbating themselves and masturbating me, back and forth. And the time she sucked her finger and then rubbed my glans, probably my urethra too.im concerned some pre cum or saliva could have entered my urethra during this exchange. Also the first day and a half of my symptoms were the worst. The evening after my appointment the pain was almost gone, today it's barely noticable so I would say it was getting better even before I started the bactrim , which I started yesterday. Is that also a good sign? Thank you doctor and sorry for the anxiety fueled rant. 

Sigh.  You are going off the deep end here.  It is not at all unusual for persons to the "trace leukocytes" in their urinalysis.  This is a NORMAL finding that typically does not warrant intervention.  It certainly is in no way suggestive of an STI.---
