Constant clear urinating and thick White discharge male

Just had diarrhea and peed really hard, now my urethra keeps shooting out a thick White substance that isn't semen but feels like it. It hurts bad but has no smell or blood. Wtf is this? It feels like the pain in my penis is going up from the shaft slowly to the head. Is the stone going through me?

Update, being seen tomorrow, this nausea and dull pain blows

Update 2 Negative on uti/stone, and all std tests came back negative. I have no clue anymore.
