Discomfort in testicles and “leaking” sensation

Patient: Hello I am a 21 year old male and I have a few questions and am very concerned. I went to the doctor due to some testicular pain and so I had some urine test and an ultrasound. My test results were negative for chlamydia and gonorrhea, and my ultrasound showed that everything was “normal”. I was prescribed Doxycycline, but after 2 weeks of treatment nothing changed. I don’t feel much discomfort in my testicles, but I do have a weird sensation in my penis, as if i were “leaking” but when I check there is nothing coming out (or at least I am not aware of it). This weird sensation usually gets worse when I’m sitting down. I already went to the doctor, but they weren’t much help. Please give me any type of advice because I am very concerned and I don’t even know what to think anymore.
