I had unprotected oral sex (protected vaginal), both gave and received with a CSW about 8 weeks ago. Since then, I have been having various kinds of issues that come and go like frequent urination, "mild" burning while urination, occasional burning on penis head, pain in groin area (no rectal pain), upset stomach, etc. I also had low grade fever initially but that is gone now. I have had all STD tests (urinalysis, gonorrhea, chlamydia, syphilis, HIV, herpes, etc.) and everything always shows up as negative.
This specific question is about a possibility of prostatitis. I had my urologist perform DRE and cystoscopy and told me that my prostate looks and feels normal. That combined with negative urinalysis makes the Dr. think that this is just in my head. However, upon "very mild" straining during a bowel movement, I notice cloudy, very sticky discharge from my penis. Now, I don't really masturbated as much as I used to, so wondering if this has something to do with it. I don't masturbate much because I feel that the burning and frequent urination gets worse hours after ejaculation. I also noticed that one of my testicles started hanging lower than the other one (that coincidentally happened with me straining a lot during a constipated bowel movement) and only sometimes feels tender. I have also been diagnosed with mild hip arthritis that just so surprisingly coincides with this incident. Reactive arthritis, maybe?
I have no idea what is going on. What could this be? What other tests should I ask for from my doctors?
