Okay, so I had unprotected sex recently. She became very dry in the middle of the intercourse and I had to use spit as lube several times. I did so over the course of two days and went for a long period of time both days but did not get to release. So when I got home I finished and relieved myself of tension, then I woke up the next day and my penis was sore but not an overbearing pain. Then I relieved myself again a couple of hours later and my urethra tube was sore to the touch and itched kind of. I am having muscle soreness in my abdominals but that is because I am currently enlisted in the Military and working out on a daily basis. No pain when I urinate, and no painful or swollen testicles. I plan on getting an STD check as soon as possible, but I was wondering if you might be able to shed some light on this. Oh and also when I m aroused but not fully erect, there is some discharge and it s clear. I m not sure if this is just the so called precum or something else. If it were a STI discharge would there be any pain and when does it occur?
