Before experiencing brown jelly in ejaculate for pass few ejaculations, had fully brown semen. And when the jelly like substance came, there occasionally comes a speck of black solid with ejaculate.
Their is blood. The black could be dried blood clots. You have to see a doc NOW. it could be a blood clot, or it could be a busted vain. Or internal bleeding. Either way it's extreme and you have to go to the ER asap.
